Decisive Classification Initiative for Monitoring products and services

Analyzers to measure constituents in various gases and fluids are each designed for specific chemicals or physical properties. Since there are hundreds of different chemicals and many physical properties there are many unique instrument designs. Laboratory instruments vary considerably from those used by field testers or those used for continuous measurement in processes.  There are many different operating principles employed.  Instruments used for stack gas measurement differ from those used at the fence line or those used for water or process fluids. The end result is that there are thousands of unique instruments

There are more than 5,000 suppliers of instruments to measure gases and fluids world wide. There are 3,000 instrument makers in China alone. Given the language inconsistencies it is a real challenge to determine which of these companies make an instrument which fits the specific needed criteria

The Mcilvaine Company is developing a system which it will make available free of charge to anyone. In return it is asking for input to make the system better. Associations, suppliers, and research institutions all have niche expertise which can be applied both to the technology and the languages. Here are the details

 A decisive classification system in Chinese, English and other languages will allow monitor purchasers in developing countries to efficiently utilize the worlds existing knowledge.  Monitoring products need to be classified by the way decisions are made.  For example the new U.S MATS rule utilizes PM mass monitors as a surrogate for measuring toxic metals. However, Pall was able to convince EPA that their multi metals analyzer was a cost effective alternative.  So scientific classification does not list PM mass monitors and multi metals analyzers as siblings but Decisive Classification does in this instance.

The system identifies monitoring products by application (there is a big difference between shale oil and oil shale), function (analyzer, sample system etc.) medium (ambient air, stack gas), Properties measured, (ammonia, arsenic (measurement parameters (ppb, ppm, count) operating principle (optical, electrochemical), and mode of use (hand held, portable etc.)

It is also necessary to identify financial entities and their subsidiaries with unique numbers. Each subsidiary with unique products should have its own unique number.  It is further necessary to provide the listings in Chinese, English and other languages.

How to participate

You can participate on a one time basis or become part of a group to continually review and revise sections of the system.

Product Key Words

The classification of key words is shown in a separate attachment. Click here

You can review the words and the system and make any recommended changes. Please also state the basis for your recommended change or addition

Also indicate whether you would like to join a group to continually discuss and revise specific segments

Decisive Classification of Products

You can provide insights as the best decisive classification of products for a given need. (As per the above example it may not be the scientific classification)

Corporate and subsidiary identifies

If you are a supplier of monitoring products or services, first check out your existing listings. If these are not correct provide us with the corporate name in English and also in Chinese if possible.  Also provide the names for unique subsidiaries which have unique monitoring products.
