System used to calibrate gas chromatography instruments

System used to calibrate gas chromatography instruments
The Dynacalibra-tor Model 150 is a constant temperature system designed to generate precise ppm or ppb concentrations of chemical compounds in a gas stream, using permeation devices as the trace gas source. It is used as a reference for the calibration of gas chromatography instruments and in other instruments that measure gas concentrations.

This lightweight unit is a compact calibrator capable of delivering the precise concentrations required. A passivated Inertium-coated stainless steel permeation chamber houses the permeation device, with measured inert carrier gas sweeping the calibration gas/vapor from the chamber. The digital temperature controller maintains the chamber temperature at a set point with an accuracy of ±0.01°C, traceable to NIST standards.
