Pesticides can adversely affect human health through the food we consume but can also leach into soil and groundwater and impact us through the environment. To keep up with a complex and constantly changing regulatory environment, your pesticide analysis solution needs to keep up with your burgeoning sample load.
In today’s budget-constrained, yet highly competitive laboratory environments, the samples you’re being asked to analyze – whether food, pharmaceutical, petrochemical, or environmental – are increasingly difficult. But for some labs, having a dedicated GC for every application isn’t an option. For them, a GC that can do it all isn’t just a nice-to have, it’s a necessity
The analysis of C2 to C12 volatile organic ozone-precursor compounds can present a serious technical challenge to the analytical chemist. Low concentrations in the atmosphere coupled with the need to monitor frequently to assess diurnal variations means that a preconcentration step of the sample before analysis by thermal desorption is required. While the samples can be collected in the field and returned to the laboratory, remote, field-based analysis is desired which allows reduced data turnaround time, minimizes sample collection hardware and permits the presence or absence of VOCs to be correlated with meteorological data. In the field, low-molecular-weight C2 VOCs can be trapped on solid adsorbents if those adsorbents are cryogenically cooled.
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.
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. NIR spectroscopy used with the method outlined here can provide a rapid screening technique for detecting adulteration in herbs and spices.
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.
Nanoparticles (NPs) have been of significant interest over the last two decades as they offer attractive benefits for drug delivery to overcome limitations in conventional chemotherapy. 3 Nanoparticles can be engineered to carry both drugs and imaging probes to simultaneously detect and treat cancer. They may also be designed to specifically target diseased tissues and cells in the body. A number of nanoparticlebased cancer therapeutics have been approved for clinical use and/or are currently under development.
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.
Through the years, both industry and analytical instrumentation have advanced. With the development of new chemicals and processes, new pollutants may enter the environment. However, the capabilities of analytical instruments have also increased, allowing the measurement of ever lower levels of environmental contaminants, as well as new pollutants.
Biodiesel is seldom used neat (B100), typically being blended with fossil diesel at ratios from 5% v/v (B5) to 30% v/v (B30). Verifying the FAME content of diesel-fuel blends is an important aspect of quality control and auditing of blending and distribution operations. Because FAME has a strong infrared absorption at 1745 cm-1 due to the ester carbonyl group, infrared spectroscopy is an excellent technique for this analysis, and there are EN and ASTM® standard test methods describing the procedure
The synthesis of active pharmaceutical ingredients (API) may require multiple reaction steps that produce undesirable reaction byproducts or utilize various solvents that have to be removed from the finished product. These solvents and byproducts may be measured with headspace gas chromatography for those volatile residual organic solvents according to the USP chapter 467 method. Method USP 467 classifies residual solvents into three classes according to toxicity; class 1 solvents are to be avoided unless there is strong justification, class 2 solvents are those that should be limited due to toxicity concerns.
This work demonstrates a robust method using SP-ICP-MS technology to detect CeO2 NPs which were extracted from soil samples with tetrasodium pyrophosphate (TSPP). Over the past few decades, engineered nanoparticles (ENPs) have been increasingly used in many commercial products. As a result, more and more ENPs have been released into the environment, which raises concerns over their fate, toxicity and transport therein.
