Potentiostat Multiplexer Modifications

Commercially available multiplexed research potentiostats were modified to incorporate a chip reader and a Faraday shield for alpha-stage product testing.

High Voltage Square-Pulse Generator

A square-pulse generator was designed using Fourier Series concepts capable of producing pulses in the MHz range with voltages in the tens of KV into a capacitive load. It uses a two-channel DDS arbitrary waveform generator as a source.

Solid-State Flow Detector

Solid state, miniature, non-contact liquid flow detectors were designed to detect the presence of liquids within 1/16” O.D. tubing. Tubing is slipped through the detector which contains our proprietary non-contact sensor. These sensors have been used for the detection of liquids for filling operations in liquid chromatography and radiochemical processing as well as for air bubble detection in flow systems. Because of their non-contact nature, they can be used to detect the presence of strong acids or aggressive solvents.

Thermo-Conductivity Detector (TCD) Amplifier

A high-sensitivity differential amplifier with manual offset adjust was designed for use with both standard and specialized TCDs. An outputs for use with typical Analog to Digital Converters (ADC) was provided.
