News Allied Analytical Systems (AAS), established by the Allied Corpora­ tion, has been formed by a merger of the Jarrell-Ash Division of Fisher Scientific and the Analytical In­ strument Division of Instrumenta­ tion Laboratory. AAS offers atomic spectroscopy instruments, including atomic absorption spectrophotome­ ters, simultaneous and sequential in­ ductively coupled plasma spectrome­ ters, and arc/spark spectrometers, as well as atomic spectroscopy accesso­ ries. For more information, contact AAS at 1 Burtt Rd., Andover, Mass. 01810; 800-342-0322 or 617-470-1790. BAS Analytics, a new service from Bioanalytical Systems, offers custom analytical services and specializes in trace determinations with an empha­ sis on liquid chromatography and electrochemistry. Specific services available include determinations of catecholamines in urine and tissue, norepinephrine and epinephrine in plasma or serum, major metabolites in tissue, phenols in wastewater, amino acids in brain tissue, and thiols and di­ sulfides. The company also will devel­ op custom methods for special prob­ lems. For more information, contact

The Federation of Chromatography Discussion Groups will hold an an­ nual meeting at this year's Pitts­ burgh Conference on Monday, March 5 from 5:00 to 7:00 P.M. in the Ventnor Ε Room at the Playboy Hotel. All chromatography discussion groups in the U.S. are invited to send one or two representatives to discuss the past year's activities and future plans. For information, contact Joseph L. Glajch, E. I. du Pont de Nemours & Co., Ex­ perimental Station 328/242, Wilming­ ton, Del. 19898; 302-772-2555.

The National Bureau of Standards and CEM Corporation have an­ nounced a joint research program to develop the use of microwave energy to dissolve samples for elemental trace analysis. Conventional sample preparation procedures involve acid digestion on a hot plate, a process that can be very inefficient because sample containers for trace elemental work are frequently made of Teflon, a good insulator. In addition, open-beaker di­ gestion can be a source of contamina­ tion. Workers will determine the mi­ crowave energy absorption of com­ monly used acids, microwave heating characteristics of various types of sample vessels, and relationships be­ tween microwave power, heating time, sample size, dissolution time, and other parameters. According to NBS, microwave dissolution techniques could reduce the time required for trace analyses from several days to five to six hours.

I13-P, "Proposed Guideline for De­ sign of Clinical Laboratory Instru­ ments Relative to Power Line Dis­ turbances," is a new publication from the National Committee for Clini­ cal Laboratory Standards. The doc­ ument is intended to establish guide­ lines for manufacturers of clinical lab­ oratory instruments and to inform laboratory personnel of potential problems and possible solutions relat­ ed to power line disturbance. Single copies are available for $15 each from the National Committee on Clinical

Fused silica capillary columns with gamma irradiated bonded phases · · · produce superior chromatographic separations with greater thermal stability—even at temperatures exceeding 300°C. Extensive studies by Foxboro and leading chromatographers have shown that bonding via gamma irradiation offers superior levels of thermal stability, while eliminating the problems of possible polarity changes and residual column activity associated with organic peroxide initiated bonding methods. Foxboro manufactures and stocks for prompt delivery gamma Bond'" Capillary Columns with OV-1, SE-54, OV-1701, OV-17, and OV-225 gamma irradiated bonded phases. Most columns are avail­ able in lengths of 15, 25, and 50 metres. To learn more about our gamma Bond Capillary Columns and how they can improve separations and decrease analysis time, contact The Foxboro Company, 80 Republic Drive, North Haven, CT 06473, (203) 288-8463.
