Interscan was the first company to realize the importance of data logging in the field of gas detection, coming out with its dosimeters way back in the early 1980s. This was followed by a complete data acquisition/archiving/reporting package called Arc-Max®, introduced a few years later.
When Windows arrived on the scene, Interscan revamped Arc-Max to be based on a SCADA (Supervisory Control and Data Acquisition) engine—for enhanced reliability and compatibility with sensors besides its own.
This latest version of Arc-Max is more user-friendly, and lends itself better to customization. Process and environmental sensors can be mixed and matched more readily, and the reporting features can be tweaked to give you exactly what you want.
Virtually all common communication protocols are supported, and the new system is easier to network.
Ethylene oxide (EtO) is an essential sterilant, used for all sorts of devices that can't take steam processing. For some years, it has been fashionable to pile on this compound. Yet, pesky data—tracing morbidity and mortality of EtO-exposed workers and comparing it to the non-exposed population—shows essentially no difference (beginning in the OSHA era).
Older EtO sterilizers were used in conjunction with separate aerators, so that workers had to unload the sterilizer and place the load into the aerator. Technically, this provided an additional exposure, compared to more modern sterilizers that have built-in aerators.
One would think that such practices would logically come under OSHA, but since ethylene oxide is considered a pesticide, EPA enters the picture.
Pesticides have to be registered and re-registered, so certain new guidelines for EtO came into effect on March 1, 2010, the most important of which is to prohibit the use of separate aerators. Or, to put it more positively, only single chamber sterilizers are now to be used.
The good news for EtO, though is that EPA also found that:
[T]he benefits of EtO use outweigh the occupational risks associated with its use provided that the risk mitigation measures outlined...are adopted and label amendments are made to reflect these measures.
Interscan has posted a Knowledge Base article on this matter, and I would encourage all in health care who might be affected by the new regs, to surf on over.
Our newest Knowledge Base article gets into measurement ranges for EtO monitoring instrumentation. In so doing, we had to take a hard look at certain OSHA documents, as well as examine some literature references.
More often than you would think, references cited in a particular article don't necessarily support the contention being made. We link to a comprehensive report from 1989, and most of its content is still excellent. Too bad the authors who referenced it couldn't quote it properly.
For reasons not entirely clear, environmental product documentation—especially data sheets on environmental instrumentation—have deteriorated over the years. Back in the day, it seemed as if the people who wrote the technical specs of instruments actually knew what they were talking about.
These days, though, it is to laugh or despair. Take your pick.
Ironically, it matters not how large or prestigious the company might be that is promulgating this material. Overall, the quality of the documentation, uh, stinks.
In one recent case, accuracy, linearity, and repeatability were conflated in a manner that beggars description. I won't mention the name of the company, but it is very large and very well known.
Therefore, I highly recommend our Knowledge Base articles on
While ppmv can just be explained away as ppm by volume, and that's how parts-per-million of gases is ALWAYS expressed, µg/Nm3 opens up a number of cans of worms, and they are dealt with in the article.
"In physical science the first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it."
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be."
And, who am I to disagree? But, even the great Lord Kelvin could not have foreseen the dimensional mess that plagues environmental science.
The issue involves metric-LOOKING units such as milligrams per cubic meter being used--usually by government agencies--instead of parts-per-million. The problem, of course, is that the stupid mass per volume unit is a function of temperature (and barometric pressure), and even if the number is stated to be at, for example, 20 degrees C, it is still foolhardy.
Why? It is foolish because air quality measurements must be done in the real world, not under controlled laboratory conditions. While, we can generally assume the we are operating near the standard barometric pressure of 1 atmosphere (760 mmHg), in the real world, the temperature isn't always 20 deg C, is it?
More than that, many people are unaware of the temperature dependence, and use "simplified" formulas to convert between parts-per-million and milligrams per cubic meter. The formulas are simplified in that they assume a particular temperature, usually 20 deg C, as well as a barometric pressure of 760 mmHg.
To help out the environmental community, we have posted spreadsheets to make these conversions ACCURATELY.
A separate Knowledge Base article is devoted to correction for atmospheric pressure differences.
