The OilExpress 4 system adapts to your laboratory’s needs, from dozens to thousands of samples per day. Its modular design makes it possible to scale up your sample throughput or separately utilize the oil dilution capabilities in busy laboratories that are using ICP analysis. The system minimizes your operational costs by reducing instrument downtime, increasing throughput to reduce cost per sample, and offering significant savings from decreased solvent waste.
Designed specifically to meet the requirements of the Caterpillar? S.O.SSM program, the JOAP program, and the new ASTM? Methods D7412, D7414, D7415, D7418, Spectrum? OilExpress is the fastest, most cost-effective Oil Condition Monitoring (OCM) solution for busy test laboratories. OilExpress also uses less than half the solvent required by competing systems, dramatically reducing day-to-day operating costs and making laboratories more competitive.
Infrared (IR) and near-infrared (NIR) spectroscopy are fast, easy-to-use techniques with a history of being used for food applications such as those for measuring protein, moisture, and fat content. Food fraud and adulteration has become of particular concern to the industry over the past few years following reports of incidents in the media, with herbs and spices identified as one of the key problem areas.
Infrared spectroscopy is particularly suitable for the identification of materials, even when the differences between the materials are subtle variations in complex mixtures. In this note we demonstrate that biodiesel from several common feedstocks can be distinguished on the basis of absorption bands arising from double bonds in the fatty acid chains.
This note describes the test method for the quantitative analysis of aerosol oil and liquid oil typically present in the air discharged from compressors and compressed air systems. The method is rapid, sensitive and cost effective and shows the FT-IR can be an effective tool for the monitoring of oil content. The methodology followed for the analysis by FT-IR is reported in Bureau of Indian Standard and we have also tested for its ruggedness, spike recovery, linearity and detection limits.
NIR Spectroscopy is a useful technique for raw materials identification and verification, but the sophistication of the technique might differ based on the sample. If the materials to be identified are spectroscopically dissimilar, it is often only necessary to use a simple distance measure such as a spectral difference for identification. If the spectra are similar, on the other hand, it may be necessary to use more sophisticated techniques which take into consideration both the intra- and inter-material spectral variation for identification and classification. The SIMCA (Soft Independent Modelling of Class Analogy) algorithm, a Principal Component Analysis (PCA) method, provides such an example.
Near-infrared (NIR) spectroscopy is an important technique for materials checking at various stages of the manufacturing process, but is particularly useful at the raw materials inspection stage. Raw materials come in a variety of physical forms including liquids, gels, and solids, requiring a versatile instrument with convenient, interchangeable sampling modules to cater to the entire range of raw materials encountered.
IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.
The intensifying global emphasis on developing sustainable fuel supplies has led to increasing use of fuels derived from biological sources. In this note we show that the Spectrum Two? FT-IR spectrometer (Figure 1) can be used to develop a quantitative method with sufficient sensitivity to meet the required detection limits for methanol, water, C3–C5 alcohols and gasoline denaturant, while requiring less than two minutes of analysis time per sample.
Olive oil is an increasingly popular food product worldwide, with global production exceeding 3.0 million tons in 2011 and showing steady annual growth. Despite these huge volumes, however, margins are relatively small in olive oil production so quick and easy analysis of oil quality is vital to maintain process efficiency. Rapid, reliable analysis can contribute to process and quality improvements in numerous ways.
Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.
The use of IR imaging expands the measurement possibilities by giving information about the individual types of materials present in the collected particles. The information from the IR imaging experiment is not only qualitative (i.e. identification of the particulates), but can also be calibrated to give quantitative information on the components present. The IR imaging measurement will take only five minutes, whereas Ion Chromatography requires solvent extraction of the particulates and would take around 20-25 minutes per sample
