Introduction
Teledyne Analytical Instruments Series 4030 Total Hydrocarbon (THC) Analyzer is designed to measure the quantity of hydrocarbons present in a heated sample gas, such as gaseous mixtures or ambient air in various industrial applications. The Analyzer is a microprocessor controlled digital instrument based on Teledyne’s highly successful Model 402R series Total Hydrocarbon Analyzer, coupled with carrier gas, a switching valve and a sample draw pump (optional). This allows for the sample into the Sample Loop kept inside a heated SAMPLE CHAMBER and maintained at a constant temperature in the range of 50 to 120 C as per application. With a
The sample integrity, as it enters the Analyzer, is maintained by ensuring that condensation does not take place inside the SAMPLE CHAMER. This is ensured by maintaining a high temperature (50 - 80°C typical) inside the SAMPLE CHAMBER. Also, the sample is diluted with the Carrier Gas to ensure that once the mixed sample reached FID, no further condensation takes place.
A separate SAMPLE SELECTOR MODULE unit (optional) may be provided for use in conjunction with the Model 4030. This allows the User to bring the heated Sample gas (Max: 120 C) and the Span gas to the Sample Selector Unit and manually select either Sample or Span for entry into the Model 4030. The User is responsible for making all gas connections from the Sample point to the Sample Selector Unit and also between Sample Selector Unit and Model 4030. The User must also ensure that gases are heated above the dew point (Max: temp. allowed 120 C) and are cleaned to better than 2 micron filter.
1.1 Main Features of the Analyzer
The Analyzer is sophisticated yet simple to use. A dual display on the front panel prompts and informs the operator during all phases of operation. The main features of the analyzer include:
