The focus of all Wilks products has always been to make affordable, easy-to-use infrared analyzers for dedicated applications. For a routine analysis of discrete components, infrared filter-based analyzers allow for a simplified, rugged instrument with no moving parts that can be used for on-site measurements and usable by non-technical personnel. Our current InfraCal Analyzer with […]
Both EN 14078 and ASTM D7371 methods for measuring the percent biodiesel in diesel fuel use infrared analysis as the analytical method and are based around using an FTIR spectrometer which has the capability to do a multitude of analyses besides the biodiesel in diesel measurement. This is great for a laboratory where various biofuels […]
As we get older, the grand schemes to force ourselves into the best we can be (thinner, healthier, nicer…) become simplified into more attainable New Year’s resolutions such as flossing every day. IR spectroscopy also has the deluxe instrumentation schemes that offer everything under the sun and the simpler versions that can make a measurement […]
Wastewater professionals who are either enforcing industrial effluent standards or trying to keep their industry from exceeding the limits for fats, oil and grease (FOG) must perform numerous gravimetric tests or spend a considerable amount of money with a contracted testing laboratory. Infrared (IR) analysis provides an alternative testing method which will significantly reduce costs […]
I recently read a comment in the Steve Jobs biography by Walter Isaacson that different divisions within a company do just what the name implies—divide a business. Integration across and communication between the departments was essential to smooth functioning product. I think the same is true in the analytical analysis/measurement world—there seems to be a […]
Water is a very strong absorber in the mid infrared (IR) region where oil is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels […]
Whether you are trying to meet effluent limits for an NPDES (National Pollutant Discharge Elimination System) permit, comply with oil and grease limits for the Clean Water Act (CWA), or an industry satisfying a POTW’s (Publically Owned Treatment Works) discharge permit, it is important to understand what could make oil in water readings vary. Listed […]
While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear. It can also increase exhaust emissions and clog filters. Typically, the suggested limit for soot is in the neighborhood of 3% but can go higher. With the new […]
Both EN 14078 and ASTM D7371 methods for measuring the percent biodiesel in diesel fuel use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectrometers. EN 14078 calls for an FTIR spectrometer with a transmission cell that is filled with the biodiesel/diesel mix. The IR light passes through the fluid and […]
I have to start by saying that I am biased toward simple fixed filter infrared analyzers when it comes to needing the same measurement over and over again. Fourier Transform Infrared (FTIR) and Raman infrared spectrometers are the Cadillacs’ of infrared analysis and do offer much more than a simple repetitive measurement. The downside is […]
