'New concept' in mid-infrared
instrumentation
This pocket-sized infrared (IR) instrument allows mid-IR spectral analysis - quantitative or qualitative - on a wide variety of materials on site, in the production area or in the field
The InfraSpec VFA-IR spectrometer, from Wilks Enterprise, now has a new 128 pixel detector array that provides expanded capabilities and better performance The 128 pixel detector array has a 1.5x improvement in resolution and a signal-to-noise ratio 75 times greater over the previous 64 pixel detector array

Variable filter array IR spectrometer for Pittcon
The InfraSpec VFA-IR spectrometer can be used like an FT-IR spectrometer; however, much of the software program has been geared towards repetitive process analysis applications.
Infrared analysers help ensure quality of biofuel
At Pittcon 2008, Wilks Enterprise will feature two portable mid-IR analysers for on-site measurements including biodiesel in diesel, ethanol in gasoline, water in ethanol, gylcerides, and FFAs
The InfraSpec VFA-IR spectrometer represents a new concept in mid-IR instrumentation which utilises a detector array with linear variable filter.
This results in a compact, portable spectrometer that has a number of advantages over conventional infrared instruments such as the widely-used FT-IR spectrometer.
These advantages include no optical path through air, no moving parts, light weight, portable (battery operated), rugged, and low cost.
The InfraSpec VFA-IR spectrometer will supplement FT-IR capability in plant or field locations where it is not feasible or economical to use FT-IR instruments.
The patented InfraSpec VFA-IR Spectrometer consists of an ATR sample plate or transmission sample stage with an elongated, pulsable source mounted close to one end and a linear variable filter attached to a detector array mounted close to the other end.
Standard variable filter ranges are 2.5 to 4.8mm, 5.5 to 10.5mm, and 7 to 14mm.
Applications include biofuels analysis, ethanol in beverages, material verification, D2O in water and transfat in oil.
The spectrometer is usable in plant, field and laboratory environments.
The InfraSpec VFA-IR spectrometer can be used like an FT-IR spectrometer; however, much of the software program has been geared towards repetitive process analysis applications.
The dedicated software provides a range of spectral processing functions and can be calibrated for quantitative analysis or materials verification.
An optional simplified interface provides numeric or pass/fail results designed to be operated by personnel having little or no knowledge of infrared analytical techniques. Request a free brochure from Wilks Enterprise ...
