  • The Universal Sampling Accessory

    Infrared Spectroscopy (IR) is one of the most descriptive “tools” available to the analytical organic chemist both for qualitative identification and quantitative determination of single and mixed components. Classically, most samples have been prepared for scanning by transmission, where the thickness becomes a very critical factor in the quality of the final spectrum. If the sample is too ...

  • Optimising next-generation lithium ion batteries with infrared spectroscopy

    Lithium batteries have become the mainstay of modern portable electronics, providing a reliable power source to run mobile phones, laptop computers and electric vehicles. Lithium technology is now even being developed on a large scale to provide electricity storage to supplement the National Grid during peak demand [1]. The issue with lithium batteries remains the same – energy density ...

  • Optical couplers: key hardware for high quality FTIR spectroscopy

    Description Optical couplers are used to take the light coming from the source of a FTIR and route it through the sampling accessory and into the FTIR detector. This is an essential process in the effective use of the FTIR spectrometer. Therefore, optical couplers play an essential role in the proper use and maintenance of a FTIR system. Recognizing the importance of optical couplers ...

  • The African crested rat’s poisonous hairs studied by attenuated total reflection infrared spectroscopy case study

    Introduction Plant toxins are commonly used by many invertebrates, as an effective defence against predation. However, such behaviour has recently been observed in a mammal.1 The African crested rat, Lophiomys imhausi, applies a potent toxin to the fur alongside its flanks. It acquires this toxin from Acokanthera schimperi,1 a shrub abundant in East Africa and dubbed the “poison arrow ...

  • Sorption of lead from aqueous solutions by tea wastes

    Received for publication March 27, 2009. Environmental contamination by heavy metals has long been a worldwide concern. Tea wastes, having porous surfaces with polar functional groups, could be a good sorbent for removal of Pb(II) from wastewaters. This study aimed to investigate the potential of tea wastes as a sorbent for removal of Pb(II) from solution and the underlying sorption mechanism. ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Water and environmental analysis according to US EPA regulations using the lambda 25/35/45 UV/Vis spectrophotometers

    UV/Vis spectroscopy is an important analytical technique used for the determination of many water constituents. Environmental regulations in many countries prescribe the use of UV/Vis spectroscopy. Depending on the method, UV/Vis determinations of metal and organic nonmetal analytes in water have a minimum detectability in the ppb-ppm range. The Lambda UV/Vis Spectrophotometers ...

  • Analysis of Automotive fluids case study

    Introduction The liquid sample is one of the most common types of samples submitted for analysis and comprises a vast array of pure compounds and solutions. As an example, several liquids are used in an automobile to sustain critical elements such as lubricating the engine or drive train and to supply mundane functions like washing the windows or generating electrical power. ...

  • Analysis of Automotive Polymers - Case Study

    The above criteria are important to the professional scientist or laboratory chemist. Introduction Polymers are present in daily life. From the wrappings around the food we eat to the sacks used for the garbage, polymers are practically everywhere. The automobile is no exception. Polymers comprise greater than 40% of a modern automobile; the carpet, seats, padding, knobs, ...

  • Soil CO2 Flux Measurements -- Using the LI-8100 System to Collect Air Samples for Estimating Soil Trace Gas Flux

    Air samples can be collected from the same air stream used to measure soil CO2 flux with the LI-8100 Automated Soil CO2 Flux System, for estimating the flux of trace gas, such as methane (CH4), ammonia (NH3), nitrous oxide (N2O), isotopic species, etc. This application note describes a simple method for obtaining air samples from the LI- ...

  • A Raman-based endoscopic strategy for multiplexed molecular imaging

    Endoscopic imaging is an invaluable diagnostic tool allowing minimally invasive access to tissues deep within the body. It has played a key role in screening colon cancer and is credited with preventing deaths through the detection and removal of precancerous polyps. However, conventional white-light endoscopy offers physicians structural information without the biochemical information that would ...

  • Speciation and mobility of arsenic in agricultural lime

    Received for publication October 6, 2008. Agricultural liming materials are used to correct soil acidity and to improve plant growth and microbial functionality. A relatively low-grade agricultural lime was found to contain up to 125 mg kg–1 arsenic (As), which is above any fertilizing materials code threshold. The color of the milled material is brown due to ample oxide dendrites. Microprobe ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Smart Infrastructure is Key for QA/QC

    Paperless, or more accurately integrated, labs enjoy streamlined operations with better data, while minimizing costs, validation and maintenance. Laboratories responsible for QA/QC are a sum of many parts, but no part is more important than data. Data is THE product, and the integrity of that data is more than critical to today’s pharmaceutical laboratories. So what happens when processes ...
