Sensitivity: 0.1 microgram (10- r gram) Capacity: 1.5 grams The Cahn GRAM Electrobalance is ideal for Spectroscopy. It will weigh all of the solid and liquid samples, with better accuracy than the analytical instrument, it will weigh the little ones more accurately than any other balance It can be used next to chopper motors, vacuum pumps, and other sources of vibration, at full accuracy. Anyone can get ultra-micro results with it.
USE IT FOR • IR samples (especially the solid ones) • UV samples (avoid costly & time-consuming multiple dilutions) • Emission samples & standards, macro & micro • NMR samples (the technique is getting more sensitive) • Raman samples

ANALYTICAL CHEMISTRY
Mass Spectrometer. An 8-page bulletin describes and gives specifications of the Type 21-703 Mass Spectrometer. This is a first order angular focusing mass spectrometer with a 60° sector magnetic field on a 12-inch radius. Designed for the analysis of solids in a wide range of applications, the instrument is available with either a Knudsen Effusion Cell or a thermal ionization source.

SCINTILLATION COUNTER AND AUTOMATIC SCALER These equipments provide a stable and accurate system for the assay of low energy Beta emitters in the liquid state, particularly Carbon 14 and Tritium. N664 Is a shielded bench-standing· scintillation counter incorporating the sample/phosphor liquid technique. The design provides optimum geometry and ready access for sample changing. Specific activities down to 10 to 10 curies per millilitre can be assayed and counting efficiencies in excess of 40% can be achieved with tritiated water samples at 15cps background. A phosphorescence filtration technique is available for background reduction. N610 is an automatic scaler and timer with an inbuilt ratemeter, pulse height analyser, amplifier and stabilised H.V. supply. The P.H.A. used with the inbuilt ratemeter provides rapid identification of energies. The P.H.A. can also be used for background reduction. In an alternative arrangement it is useful for the simultaneous assay of Double Labelled samples. The timer is used as a second scaler channel, taking an output from the upper discriminator of the P.H.A.
