WHO SAID INFRARED IS DEAD! A Visit to the Wilks booth at the Pittsburgh Conference will prove that it isn't
Infrared is alive and kicking — especially at Wilks Scientific. Infrared analysis is becoming more precise, more automated in the laboratory and it is moving into such diverse applications as food process monitoring, toxic vapor measurements, atmospheric studies, police work, and analytical control of chemical processes. The trend in instrumentation is toward small, portable packages with sample systems dedicated to particular applications. We are working in this direction and will have a lot to show you at Cleveland. For example:
IR and Micro Processing We have been programming the new MIRAN 1A for multicomponent analyses and for material identification by numerical pattern recognition using micro data processing circuits. While we won't have much in the way of equipment to display, we will have much interest in potential applications and would like to hear about yours. The MIRAN 1A has an improved wavelength selection mechanism and is sealed and purgeable. It is ideal for repetitive quantitative measurements. CIRCLE 246 ON READER SERVICE CARD
Process Control by "Analysis" For years, process control by stream composition rather than by temperature, pressure, and flow rate has been just over the horizon. Well, analytical control is here and its arrival is most timely — with the radical increase in the cost of raw materials, a few percent increase in processing efficiency can spell the difference between profit and loss. We have learned a lot about continuous analysis of process streams — especially liquids — and many of our MIRAN II systems are on-stream providing data for closer process control. We will display new flow cell assemblies and automatic extraction systems for oil-in-water and other determinations.
"Super" Supernoses Nearly 1,000 twenty meter cells — the original "supernose" — have been built by Wilks Scientific in three years. During the past year, 1 meter and 40 meter models have been added to the family. We will be exhibiting the latest edition, a cell with a nominal path of 120 meters — although we have run it up to 200 meters — which is truly a "super" supernose. Its use may require some modification of laboratory ceilings, but for those applications requiring the ultimate in sensitivity, the new 120 meter cell may be the answer.

Ambient Air and OSHA
Infrared is Very Much Alive
Almost weekly, OSHA and NIOSH are undertaking new investigations of materials on their toxic vapor lists. OSHA is equipping its inspectors with more and more sophisticated instruments and it is incumbent upon industry to do likewise. Infrared analyzers are the most specific and convenient instruments to measure toxic vapors in situ. We will unveil two new ambient air monitors: The MIRAN 101, a self-contained, battery-operated analyzer, weighing less than 18 pounds and sensitized and calibrated for a specific vapor; the MIRAN 201, a stationary area monitor capable of monitoring toxic vapor concentrations at up to 15 remote locations. MIRAN 101 reads directly in ppm of the material in question. MIRAN 201 does the same but, in addition, can be equipped to print concentration versus time for each station, thus satisfying OSHA requirements for record keeping.
Bring your analytical problems to our booths (1010, 1012, & 1014) and we will show you how the new breed of "dedicateable" IR analyzers can help solve them. If you can't make the Pittsburgh Conference, send them to us and we will arrange a demonstration. The ancient art of infrared analysis is as viable as ever!
