ANALYTICAL CHEMISTRY
S e e item
The non-overloading linear amplifier, Model 215, is recommended by BairdAtomic for pulse height analysis of xrays in the presence of high energy gamma rays because it is designed to amplify small pulses in the presence of much larger overload pulses. 3 Infrared Family Expanded
A new addition to its growing family of infrared instruments was introduced at Pittsburgh by Beckman Instruments, Inc. This latest member, shown on page 81A by E. P. Evans of Beckman, is the IR^5 infrared spectrophotometer, a lowcost, double-beam instrument, selling for less than $5000. It is a null-rtype single monochromator instrument, featuring a horizontal type X-Y recorder, hermetically sealed optics, and both single and double beam operation. Fixed operating parameters simplify operation. According to the company, the instrument has a minimum of controls and produces reliable spectra with a scanning time of 16 minutes for the 2 to 16 micron region. 4 Power Supply for Spectrophotometer
Beckman Instruments also announced a new power supply for use with the DTJ spectrophotometer. The power supply is said to eliminate the need for the storage battery and the -dry cell batteries while providing all the power needed to operate the DU spectrophotometer. I t also furnishes power for the DU hydrogen lamp and makes the power supply unit of the ultraviolet accessory set unnecessary. 5 Electropolarizlng Instrument
Boder Instruments exhibited the new Patwin recording electropolarizer, demonstrated by J. G. Waltz, company representative. This low cost instrument features the following: an initial polarizing bridge which can be set with 4.5 inch, 1% voltmeter or standard cell; a span voltage bridge
