PHS Training Courses The Public Health Service, through its Division of Occupational Health, will conduct a series of related train ing courses October 9-27, 1961, at the Occupational Health Research and Training Facility, Cincinnati, Ohio. In dustrial Hygiene Engineering, designed for industrial hygienists and engineers in the field of occupational health, and Industrial Hygiene Chemistry, for chemists and chemical engineers in this field, are given concurrently, October 9-20. Trainees in both courses meet together for the first week for instruc tion in industrial hygiene and medicine, toxicology, and principles pertaining to the evaluation of the environment. Meeting separately the second week, work for the chemists covers laboratory analyses for lead, free silica, and sol vents; spectroscopy, polarography, xray diffraction, electron microscopy, and gas chromatography. Much time in both courses is spent in the labora tory. A related course, Ion Exchange Tech niques for Fluorides and Mercury, fol-
How to Trap a Half Microliter Q.C. Fraction — and analyze it by Infrared... Chromatography separates, infrared identifies — if you can get the GC fraction into the infrared beam! That's a big "if" because the volume of the GC fraction is usually well under a microliter. A CIC specialty is trapping equipment for IR analysis of GC fractions. The most recent development is a series of micro gas cells contoured to match the infrared beam and rugged enough to stand direct cooling and heating. They may be immersed in a cold trap, the carrier gas from a chromatograph passed through them, and the fraction frozen out. They may then be heated so that the fraction is re-vaporized and transferred to the spectrophotometer for analysis. In addition to the micro gas cells, CIC also makes ultra-micro liquid cells and liquid fraction collectors. If the combination of GC and IR is of interest to you, we will be glad to send you more information concerning our equipment.
