The GFC Series gas filter correlation analyzers measure low ranges of gases (CO, CO2 and N2O detecting models available by comparing infrared energy absorbed by a sample to that absorbed by a reference according to Beer-Lambert Law. All GFC Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel or via RS-232, Ethernet or USBcom ports either locally or by remote connection using the included APIcom™ software.
Gas Filter Correlation Wheel
By using a gas filter correlation wheel, a high energy IR light source is alternately passed through a target gas filled chamber and a chamber with no target gas present. The light path then travels through the sample cell, with a variable length folded path depending on the gas being detected. The energy lost through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range.
