Acetaldehyde Analyzer With 20-ppb Detectable Limit
The Series 200ACE Acetaldehyde Analyzer monitors trace oxygenate impurities for the carbonated beverage industry, and exceeds all ISBT Method 11.0 criteria for selective measurement of acetaldehyde (CH3CHO) in CO2. Continuous operation, coupled with proprietary technology, is used for the specific measurement of CH3CHO without interference from other potential impurities in beverage-grade carbon dioxide. Detector response is linear over 5 orders of magnitude. The lower detectable limit for CH3CHO is 20 ppb, well below the ISBT guideline limit of 200 ppb. Acetaldehyde is speciated, captured, compared against a previous standard run, with results displayed digitally on the instrument's front panel. The run takes less than 5 minutes, interference free. The flow system combines transport, calibration, and sample gas movement with discreet sample introduction and speciation capability. The onboard software package allows complete unattended operation of the analyzer with a few simple input commands to the keypad on the instrument's front panel. All functions, including status notes, are clearly displayed on the front of the instrument so that the progress of each calibration, validation, and/or analysis can be monitored.
