The Model 55C is designed to provide a direct measurement of both
methane and non-methane hydrocarbons without the use of scrubbers or catalysts
from 0-5,000ppm. The proprietary column design is unaffected by oxygen and
provides complete recovery of low volatility compounds.
Product Detail
The Model 55C, Direct Methane, Non-Methane Hydrocarbon Analyzer, joins Thermo's line of hydrocarbon detection instrumentation. Offering a unique blend of proven technology with innovative hardware and software design, the Model 55C possesses unsurpassed sensitivity, repeatability and specificity in ambient and source applications.
Direct measurement always produces the most precise result. That's why the Model 55C is designed to provide a direct measurement of both methane and non-methane hydrocarbons (NMHCs). Unlike instruments that use scrubbers or catalysts to measure only methane and total hydrocarbons, the Model 55C back-flushed gas chromatography system allows reliable measurements of NMHCs at sub-ppm concentrations of methane. In addition, the Model 55C's proprietary column design can achieve complete separation of methane from all C2 compounds, is unaffected by the oxygen recovery of low volatility compounds that other instruments may miss.
Added to the accurate reporting is an easy to read, intelligently designed display that allow the operator to monitor instrument status and current concentration readings at a glance. The high visibility vacuum fluorescent display indicates the current ppm reading, the sample injection time, the instrument operation mode and various status messages so you always know exactly what you are getting for results.
Thermo's menu-driven software, which enhances all of our products, makes it simple to establish operating parameters and to control calibration and measurements. The menu is easy to access using the front panel controls, or by the optional RS-232 communications system and PC based software. The Model 55C also provides analog status and control lines for use with an external data system and it may be configured for continuous, fully automated, stand-alone operation.
