• 2 to 3 Times Better Noise Performance. This permits integration for longer periods of time and
detection of smaller changes in absorbance. The charts below show 3x noise improvement for the
NIRQuest512 over the NIR512 at a 10-second integration time.
• Considerably Better Signal-to-Noise Ratio (now >15000:1 at 100 ms). This allows better
detection in low light levels, use of a smaller slit size (provides higher optical resolution without
sacrificing throughput), and simpler measurement of higher concentration samples.
• True External Trigger with a fixed 1-ms delay after an external event before integration begins.
• Thermoelectric Cooler stabilizes after 1 minute in the NIRQuest 512 vs. 2 minutes in the NIR512.
• More Grating Options are provided (up to 6) to better optimize your application setup.
