Translation has released the DT9821 and DT9822, ultra-high resolution USB chromatography modules that can resolve from 60 parts per billion at 24 bits to 1 part in 65,536 at 16 bits.
Data Translation has released the DT9821 and DT9822, ultra-high resolution USB chromatography modules that can resolve from 60 parts per billion at 24 bits to 1 part in 65,536 at 16 bits. These multifunction modules are targeted to a variety of industries such as environmental, pharmaceutical, life sciences, separation sciences, biotechnology, chemical, power generation, and electronics.
The modules offer variable input resolutions from 16-bit at 960 Hz to 24-bit at 7.5 Hz, giving users the versatility and power range to sample at higher speeds where less resolution is needed and lower speeds where greater accuracy is required.
The DT9820 Series also has four separate 24-bit A/D time-based independent input channels that can be started and stopped independently of each other, or even run at different sample rates.
Such flexibility means that individual channels can be added or removed from the scan list while the ADC is running to support industry standard time base independence.
"The DT9821 and DT9822 modules are ideal for applications detecting very small differences in the presence of large signals.
While chromatographic output is not considered particularly dynamic, it does require very high resolution to detect minute amounts of compounds whose peaks lie within the wings of predominate components.
This is a challenging data acquisition and analysis task," said Tim Ludy, Data Translation1s Product Marketing Manager for Data Acquisition.
As a plug-and-play connection, the modules can be easily transported and used virtually anywhere, whether it be a chemical laboratory or a manufacturing floor.
In fact, chromatography applications today are serving a wider audience, from environmental agencies responsible for establishing the quality standards of ISO 9000 and ISO 14000 to scientists furthering HIV studies.
