3.3 Sampling Considerations
3.3.1 Sampling Point Location
The ACCUCHROME Natural Gas Chromatograph should be located at a point as close as
possible to the stream being analyzed to avoid lag times and sample degradation in the
delivery line. The samples sent to the analyzer must be representative of the stream.
3.3.2 Sample Volume and Flow Rate
The sample should be supplied to the analyzer at a maximum pressure of 100 psig. A flow
meter at the analyzer will control the flow into the analyzer's sample valve at 50cc/min. A
bypass sweep is recommended to reduce lag time in the sample lines.
3.3.3 Sample Conditioning
An optional sampling system is available with the ACCUCHROME Natural Gas
Chromatograph to regulate and filter the sample. The sample system is required if the
sample is not available at a pressure less than 100 psig, contains particulates, or is subject to
liquid dropout. Consideration must be taken of normal conditions as well as abnormal
conditions when designing the sample system as contamination may be an issue. Please
contact Galvanic Applied Sciences for assistance.
3.4 Electrical Requirements
The ACCUCHROME is available with 24 VDC power input or 90-240 VAC power input.
The power consumption is approximately 100 watts at start-up and approximately 50 watts
when running at constant temperature.
