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
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.
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.
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.
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.
Liquid chromatography-tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide The state of Oregon has issued regulatory limits for 59 pesticide residues in both cannabis flower and concentrates, while other states have come up with
Water polluted by herbicides leach and runoff can cause human health problems including cancer tumors, reproduction deformity, disruption of the endocrine system and DNA damage. This application presents a sensitive and robust liquid chromatography method to test nine widely used herbicides (Figure 1), using a 3 μm UHPLC column to achieve very high throughput at a low flow rate to reduce testing time and solvent consumption. The throughput is compared to that of a conventional C18 HPLC column. Method conditions and performance data including precision and linearity, are presented.
Measuring the amount of metals in CNTs presents a challenge. High levels can be measured directly in the solid by several techniques, including XRF and TEM, while low-level analysis requires complete digestion of the sample prior to analysis by ICP-OES or ICP-MS.
In this work, we demonstrate that PerkinElmer's NexION? 2000 ICP-MS, with its unique RF generator and ion optics, coupled with the Syngistix? Nano Application Software Module, can be used to accurately measure and characterize NP sizes of 10 nm and smaller, both alone and in a mixture of NPs of various sizes.
A gas chromatographic analysis of the extract can provide even greater sensitivity and more detailed compositional information, but further increases the time required for the analysis. Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) can provide detailed information about the amount and nature of the pollution, while requiring no sample preparation at all. This application note illustrates the kind of data that can be obtained with a modern TG-IR system.
Ginseng has been used as an herbal medicine in Asia for over two thousand years for its purported various health benefits, including, antioxidant, anticarcinogenic, antiinflammatory, antihypertensive and anti-diabetic. The pharmacologically active compounds behind the claims of ginseng’s efficacy are ginsenosides; their underlying mechanism of action although not entirely elucidated appears to be similar to that of steroid hormones. There are a number of ginseng species, and each has its own set of ginsenosides.
With heavy machinery, it is important to assess its status during operation to prevent breakdowns and costly repairs. A key aspect is monitoring the status of the oil or lubricants used to lubricate various components such as engines, transmissions, gearboxes and many other important areas: if the oil degrades too much or becomes highly contaminated, it can damage various components. Because of its importance, ASTM created a method for the analysis of in-service oils: method D5185.
