A new concept in mid-infrared
instrumentation
The InfraSpec Variable Filter Array VFA-IR Spectrometer now has a new 128 pixel detector array that provides expanded capabilities and better performance in laboratory, plant and field
This 'pocket-sized' (6.5 x 4.5 x 1.5inch) infrared (IR) instrument allows mid-IR spectral - quantitative or qualitative - analysis on a wide variety of materials on site, in the production area or in the field 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

New variable filter array IR spectrometer
Wilks Enterprise will introduce a new InfraSpec VFA-IR Spectrometer with a 128 pixel detector array that provides expanded capabilities and better performance at PITTCON 08
The InfraSpec VFA-IR Spectrometer represents a new concept in mid-IR instrumentation which utilizes a detector array with a 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 (under 5 lbs), 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 4.8 mm, 5.5 to 10.5 mm, and 7 to 14 mm.
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 programme 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.
