Gas Filter Correlation Carbon Monoxide Analyzer
Model T300
The Model T300 measures low ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 14 meters. The energy loss through the sample cell is compared with the span 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 extreme sensitivity. All T 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 RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Low Temperature Operating Life (LTOL) Test
LTOL
LTOL is being more used more and more frequently by manufacturers of low geometry devices as part of the qualification process, and in order to gain more failure data, a greater understanding of different failure modes of the device at low temperature, and to enable more complete reliability estimations. As device geometries decrease and frequencies become higher, Hot Carrier Injection (HCI) increases and the resulting degradation causes the deterioration of device characteristics and ultimately leads to failure.
