Wide Dynamic Range
Low-noise electronics and an 18 bit A/D converter double the QE Pro’s dynamic range
and increase the sensitivity by a factor of two compared to typical back-thinned CCD
array miniature spectrometers. These enhancements drive applications benefits such as
improved lower limit of detection for both absorption and fluorescence measurements
and enable measurements over a wider concentration range.
Buffering for Fast Measurements
To support fast, and full-spectrum data acquisition, the onboard buffer stores up to
15,000 spectra. This maintains data integrity by buffering time stamped spectra for USB
communications. Buffering enables full-spectrum kinetics measurements to be performed
every 8 milliseconds or 125 measurements per second.
Reliable Performance
Thermoelectric cooling (TEC) precisely controls the temperature of the detector.
Cooling the detector dramatically reduces the effect of thermal noise and improves
overall the stability of the detector for lengthy measurements. The TEC in the QE Pro
holds data stability to 4 dark counts over a 60 °C ambient temperature range, giving you
the highest quality data. This stability performance makes the QE Pro ideal for demanding
online and at-line quality control measurements susceptible to temperature changes.
Kinematic mounts are used to position the optical elements of the QE Pro to increase
accuracy and reliability. New RS-232 communication protocols allow the QE Pro firmware
to be updated in the field, ensuring you have the most up-to-date product.
The high-sensitivity QE Pro is a good option for measuring the Raman
shift of aromatic hydrocarbons such as toluene.
