Wilks Enterprise, Inc., founded in 1995, specializes in the development and manufacture of infrared (IR) analytical instrumentation for dedicated quantitative applications. While these instruments have been specifically designed for on-site field or at/near-line use, they are equally as useful in the analytical or testing laboratory - virtually anywhere repetitive quantitative infrared measurements are needed. And, they are the ideal choice for supplementing the capabilities of FT-IR Spectrometers in areas where it is not practical or economical to utilize such sophisticated and costly instruments. Analyses are made by measuring the amount of energy absorbed by the sample at one or two specific mid-IR wavelengths. Fixed band pass optical filters are used to isolate the wavelengths and the resulting instruments are called infrared filtometers and carry the Wilks Enterprise tradename InfraCal Filtometers or InfraRan Specific Vapor Analyzers. Their newest instrument, the InfraSpec VFA Spectrometer utilizes a detector array with a linear variable filter which enables users to obtain spectra of a variety of materials wherever they occur - at/near the production line or in the field. The new spectrometer is “pocket-sized” (5” x 5” x 1.5” in size) and is capable of producing near or mid IR spectra on powders, films, liquids, slurries, semi solids and solid surfaces. Standard InfraCal Filtometers include their line of TOG/TPH Analyzers which are used worldwide for measuring total oil and grease (TOG) and total petroleum hydrocarbon (TPH) concentration levels in water and soil; or their Soot Meter Plus for rapid on-site or laboratory measurement of soot levels in diesel engine lubricating oils. But this is only the beginning – you can use an InfraCal Filtometer for virtually any dedicated mid-infrared quantitative analysis. They are being used to: Check cleaning efficiencies on metal parts Analyze methanol and similar materials in water Measure organic or inorganic coating thickness on metal substrates Determine principal ingredient content, including water, in household and personal care products Measure D2O in water and water in D2O Monitor CO2 concentration levels in liquids Determine EVA and Nylon layer/thickness in polyethylene films The new InfraRan Specific Vapor Analyzers are low cost, factory-calibrated IR instruments for the detection and measurement of contaminants in ambient air. User-friendly, menu-driven software and portability make on-the-spot detection and quantitative measurement of a single gas or multiple gases fast and easy. They are ideal for OSHA compliance testing, plant surveys, and most ambient air monitoring applications. IR analysis is a very versatile and practical analytical tool with many broad applications in quality control, process monitoring, environmental measurements or material verification. Whatever your IR application, chances are an InfraCal Filtometer, InfraSpec VFA-IR Spectrometer, or InfraRan Vapor Analyzer can help you do the analysis more effectively, make the measurement on-site where it is needed, and save you money -- at the same time.
