Easy on-site measurement of the percent (%) alcohol concentration level in beverages is now possible with a new portable infrared spectrometer, the InfraSpec VFA-IR spectrometer from Wilks Enterprise
Alcohol measurements by current methods, such as gas chromatography or distillation, can be a lengthy laboratory process requiring technically trained personnel.
With the InfraSpec VFA-IR spectrometer, the measurement can be handled on-site in approximately one minute, without sample preparation, and by technicians with little or no infrared spectroscopy knowledge - all at a fraction of the price of traditional instrumentation.
The InfraSpec Spectrometer represents a new concept in portable mid-infrared instrumentation, utilizing attenuated total reflection (ATR) sampling technique to measure the percent of alcohol in beverages.
The exposed ATR crystal on the built-in sample stage makes analysis and cleaning quick and easy.
With a simple interface for non-technical operators, a material is placed on the ATR sample stage and a digital readout in % alcohol is shown in about one minute.
The measurement range is 3% to 95% with an accuracy of <1.5% of scale.
The InfraSpec VFA-IR spectrometer incorporates a patented design consisting of an ATR sample plate with an elongated, electronically modulated source on one end and a linear variable filter (LVF) and linear variable array on the other.
The result is a compact spectrometer with no moving parts, no optical path exposed to air that is portable and rugged.
The software includes an internal calibration program that allows for simplified screen interface that give a digital readout in % alcohol for non technical end users.
