ETHYLENE OXIDE (EtO) MONITORING SYSTEMS

As regulatory requirements and enforcement bear down on your facility, you need a reliable, accurate, and cost-effective way to monitor ethylene oxide. Why not partner with a world leader in toxic gas detection?

Only INTERSCAN CORPORATION offers a full range of monitoring instrumentation for ethylene oxide--from portable analyzers to multipoint systems--along with the industry`s best data acquisition, archiving, and reporting system--Arc-Max®.

Field proven in thousands of installations, Interscan EtO monitors offer you...

  • Excellent sensitivity, specificity, and accuracy
  • Ease of use and reliability
  • Unmatched performance and peace of mind

You might already be using badges, but badges can`t protect your area with an instantaneous alarm, and even though they can provide exposure data, it`s incomplete. Badges give you only a ``single number`` of accumulated exposure, with no time history! What if your employees got a heavy exposure of EtO on certain days during a badge cycle, with no exposure on the rest of the days? The badge would still read ``normal.`` Thus, with badges, you are unable to track the effects of a particular incident.

You might have an older EtO monitoring system installed, that needs to be updated, since it is prone to false alarms, or is simply not sensitive enough to meet today`s standards.

You might have a perfectly fine EtO monitoring system installed, but you want the benefits of adding data acquisition, archiving, and reporting. High concentration alarms are only a part of the total picture! You should also keep track of long-term low level exposure--the basis of far too many lawsuits. Unless you have a documented record of employee exposure to EtO, if you`re sued, you`ll be scrambling for data, desperately trying to re-create the past. There`s no better way to keep these records than with Interscan`s Arc-Max®.

So, whatever your requirement might be, INTERSCAN is the only name you need to remember for ethylene oxide monitoring.

GETTING STARTED IN EtO MONITORING

The most important precept in ANY toxic gas monitoring application is protecting the employees. All decisions to determine the number and location of sampling points must be made with this in mind. Therefore, as a first priority, you must monitor where people are working.

Beyond that, consider...

  • The sterilizers and aerators
  • Drain areas
  • Gas cylinder storage area
  • Ventilation characteristics
  • Any other leakage or exposure possibilities

After the number and location of sampling points has been determined, options can then be evaluated and specified. Based on a thorough review of your unique monitoring requirements, Interscan will propose a system that fits your budget and does the job.

As a general guideline, most systems contain 2-4 points of detection. A single point system would be deployed in either a very small Central Service department, or because of budgetary constraints, absolutely limiting the scope of the system to monitoring the work area only.

Interscan`s website www.gasdetection.com contains a wealth of information on the basics of toxic gas detection. A special section is devoted to ethylene oxide issues:

As system integrators and custom instrument designers, we often incorporate high quality sensors from others into specialized packages--ideally suited to the application. That`s why Interscan is your one-stop source!

What About Measuring Ranges?  

Available measuring ranges, in all cases, provide sufficient sensitivity to operate well below the applicable occupational health levels, and, at the other end, allow readings in excess of 1000 ppm.

Does Interscan Offer Free Applications Assistance?    

Absolutely! Interscan has unmatched applications expertise, and an installed base of hundreds of thousands of instruments. We know how to solve your gas detection problem!

Data Logging and Archiving Products  

Detection and tripping alarms are fine, but you also should consider keeping a record of employee exposure.  Interscan offers two products for occupational health record-keeping:

Nomad Data Logger

The Nomad is a self-contained data logger that connects to any instrument with an analog output, and samples and stores its output at a rate adjustable from once per second to once every 10 hours. The unit is supplied with all necessary cables and excellent software, that produces a variety of reports and allows export of the data files.

Nomad models with built-in sensors are also available for temperature, pH, pressure, and many other parameters.

Arc-Max® Data Acquisition, Archiving, and Reporting Package  

Arc-Max® continuously stores input from all kinds of workplace sensors, and produces reports of employee exposure to toxics, automatically. Built around a powerful SCADA (Supervisory Control and Data Acquisition) engine, alarm logs, live and historic trending, and specialized reports--Shift Reports--giving key occupational health information, are available at the click of a mouse. Up to four independent shifts per day can be assigned, to better analyze exposure data. The shifts can overlap. The Shift Reports can be programmed to print automatically at the end of each shift, or on-demand at any time. Historical Shift Reports are readily available, as well.

For a more in-depth look at what we have to offer, log onto our website   www.gasdetection.com. There you`ll find links to our portable gas analyzers, continuous monitoring systems, and data logging/data acquisition products, along with a host of useful technical information, geared to gas detection.

Your next step? Use any means you like to contact one of our applications engineers, for more details, or a quick-response quotation.

We invite you to discover how INTERSCAN is your one-stop source for the finest in gas detection instrumentation!


Portable EtO Analyzer


Ethylene Oxide Monitoring Systems

Arc-Max takes full advantage of the field-proven MicroScan 2000 SCADA (Supervisory Control and Data Acquisition) engine, to reliably produce alarm logs, live and historic trending, and specialized reports-- Shift Reports--giving key occupational health information.

Up to four independent shifts per day can be assigned, to better analyze exposure data. The shifts can overlap. The shift reports can be programmed to print automatically at the end of each shift, or on-demand at any time. Historical shift reports are readily available, as well. The Shift Report tracks the following, for each sensor monitored by Arc-Max®.

  • Shift minimum value and time of occurrence
  • Shift maximum value and time of occurrence
  • 8 hour time-weighted average
  • The four highest 15-minute average exposures that occurred during the shift (STEL)

Why Do You Need Arc-Max?    

Toxic gas detection and alarming have been an accepted part of any good occupational reporting, safety and health program for many years. Just as important, if not as well publicized though, is the need for appropriate data acquisition, archiving and reporting.
That`s where Arc-Max comes in.

Suppose that you`ve been a good corporate citizen, and have installed sensors for toxic compounds all around your facility, to protect your employees. Ask yourself this: Can you document long-term employee exposure? Do you have any idea how close their exposure is to the allowable levels? High concentration alarms are fine, but they`re not enough. Of greater importance these days is long-term low level exposure.

That`s the kind of exposure that lawsuits are based on. Unless you have a documented record of exposure, if you`re sued, you`ll be scrambling for data, desperately trying to re-create the past.

The Arc-Max® Advantages     

  • Arc-Max is completely self-contained: Unlike most competitive systems, Arc-Max produces the reports you need directly from the program. There is no need to export files to a spreadsheet program, unless you want to do unusual or specialized analysis. What`s more, all reports are generated without interrupting the current data collection.


  • Arc-Max is easy to use: The system is supplied totally configured for your application, and is ready to run--right out of the box. No programming is required. All you do is connect your inputs.


  • Arc-Max has data integrity: Because of the advanced program design, there is little chance of anyone ``tweaking`` the data after the fact. All sensitive functions, including setting alarm levels, establishing shift times, and exiting the program itself, are under password access.

Simply put, there is no package on the market today—even at twice the price—that can compete with Arc-Max! Click on the following links and see for yourself screen shot images of features such as Current Data Report, Shift Reports, Trending and Alarm Log.

This brief introduction covers the main features, but by no means all the features, of Arc-Max®. For the full story, you are invited to contact our sales department.



Research has indicated that hydrogen sulfide, methyl mercaptan, other thiols, and dimethyl sulfide, collectively referred to as volatile sulfur compounds (VSC), are the principal malodorants in chronic halitosis. These compounds are generated by anaerobic bacteria, located principally on the back of the tongue. The American Dental Association confirms that millions of people suffer from this condition in the United States alone.

Chronic halitosis is to be distinguished from the short-term variety that most people experience after eating odoriferous foods.

Although sophisticated and expensive instrumentation methods have occasionally been employed to determine VSC, Interscan`s Halimeter® is the first unit specifically designed to measure VSC in a clinical setting.  Accurate measurements of VSC form the basis of diagnosis and treatment of chronic halitosis.

Prior to its acceptance as a tool by dental practitioners, the Halimeter® was used as a measuring device in dental research studies. Correlating well with organoleptic assessments (evaluations by a panel of odor judges), the Halimeter® enables measurements of bad breath to be quantified in parts per billion (ppb).

Click here for the United States Food and Drug Administration (FDA) status of the Halimeter®.

The Halimeter® is intended to be utilized as part of a total program, encompassing a thorough history and physical examination of the patient. Our Experts' Forum features many useful articles on diagnosis and treatment modalities, including excellent clinical charts.

The emotional involvement of many patients with chronic halitosis, as well as the possibility that underlying conditions may be present, require that the practitioner follow a well-established diagnosis/treatment protocol.

The Halimeter® has found its greatest acceptance as a result of the recognition that chronic halitosis is nearly always a dental problem. Complementing this is the availability of special formulation mouthwashes and tongue cleaners which remove the VSC`s and may also kill the offending bacteria.

In just a few short years the Halimeter® has become the premier instrument for chronic halitosis research, diagnosis, and therapy. Used by over 3,000 dentists in private practice and academia, the Halimeter® offers greatly enhanced patient outcomes, as well as profitable opportunities, in the treatment of oral malodor.



What if you want to do some serious data logging, but don`t need the multi-channel capabilities and permanently installed configuration of Interscan`s Arc-Max®?

Then check out our Nomad Data Loggers.

Nomad models are available for a variety of voltage and current inputs, along with self-contained units for temperature, humidity, pressure, and pH. Data sampling rate is customer-adjustable from once per second to once every 10 hours--in 1 second increments.

Supplied with easy to use software, the analog input loggers can be programmed to record in engineering units, and yield a number of useful reports.
