T
he Model 3120 Series is a new product being offered
for use on Gas Chromatographs and other scientific
instruments. The Model 3120 Series regulators have
been designed with a reduction in the internal dead space of the
regulator and a reduction in the quantity of non-metal parts. The
dual stage design of the product ensures accurately delivered
pressures over the usable life of cylinder gases.
The Model 3120 Series regulators are recommended for use in
applications requiring high purity delivery of gases in a non-corrosive
environment. These applications typically include use of the regulators
for high purity carrier gases, calibration standards and GC applications
using PID, HID or ECD detection methods. The reduced dead space of
the regulator and the reduction in non-metal parts ensures high purity
control of gases. The Model 3120 Series is compatible with gases that
are non-corrosive in nature and gases that are compatible with the
materials in the process stream.
