Anasys Instruments reports on the study of cultural heritage painting cross-sections by researchers from UCSB and the Getty Conservation Institute using their breakthrough AFM-based nanoscale mass spectrometry technique.
The analysis of cultural heritage materials presents a number of challenges such as: limited and extremely small samples, complexity of sample structure, the importance of maintaining spatial integrity and, most notably, the rarity of the samples. These limitations present specific challenges for the identification of many traditional organic dyes, particularly in paintings that may have multiple original paint layers (depending on the artist’s...
A new whitepaper from Malvern Instruments on Oral Solid Dose (OSD) deformulation demonstrates how the analytical technique of Morphologically Directed Raman Spectroscopy (MDRS) can be used to accelerate the development of generic products to a successful conclusion.
Deformulation, the unpicking and investigation of a reference labeled drug (RLD), enables generic developers to understand the features of a product that define its clinical performance. “Accelerating the deformulation workflow for oral solid dosage forms” reviews the current regulatory landscape associated with generic development and considers the workflow for preparing OSD product Abbreviated New Drug Applications (ANDAs)...
Researchers at the University of Lethbridge, Alberta, Canada, are using Viscotek multi-detector Gel Permeation/Size Exclusion Chromatography (GPC/SEC) (Malvern Instruments, UK) to analyze performance defining polymer features in the development of novel polymer coatings for metal nanoparticles.
“Multi-detection GPC/SEC helps us to monitor and control reaction conditions to engineer advanced polymer coatings which stabilize nanoparticle suspensions to ease their handling and preserve their industrial value,” said Dr. Farhad Faghihi, Research Associate at the University of Lethbridge. “GPC/SEC is the only technique that we have to determine molecular weight and molecular weight distribution with the speed and accuracy...

The globalization of the food chain has meant that the focus on food safety is greater than ever before and as a result, food manufacturers are facing increasingly stringent regulatory requirements.
One area that is receiving a growing amount of attention is mycotoxin intake from contaminated food and feed which causes mycotoxin intoxication. Mycotoxins are secondary fungal metabolites that are typically produced by fungi growing on grains and fruit during shipment or storage. When ingested, mycotoxins may cause acute or chronic disease and it has been shown that repeated exposure to low level mycotoxin ingestion can affect...

J.G. Finneran Associates designed Limited Volume Inserts with and without Bottom Springs to ensure that autosamplers extract even the smallest sample volumes every time, without damaging injection needles or breaking sample containers.
The inserts preassembled with polymer bottom springs act as shock absorbers to protect sample needles from bottoming out during sample extraction. Inserts without the bottom springs automatically centers in the vial and provides a perfect seal with the septa. The pulled point internal design permits sufficient sample withdrawal and allows chemists the ability to analyze smaller sample volumes in standard size vials.

Since its introduction into the market, High-Resolution Continuum Source (HR-CS) AAS has revolutionized the world of spectroscopy.
contrAA® instruments provide this technology for Flame, Graphite Furnace and Hydride analysis, including solid AA®. With the latest technical and software upgrades HR-CS AAS becomes even more powerful. Now also simultaneous evaluation of multiple element wavelengths is possible. As the Xenon lamp as continuous radiation source allows to use any wavelength, non-metals and "classical" AAS elements can be analyzed together in the same...
Thermo Fisher Scientific has developed an ion chromatography method with suppressed conductivity detection for sensitive determination of inorganic anions and carboxylic acids (fluoride, acetate, formate, mesylate, chloride, nitrate, succinate, malonate, sulfate, and oxalate) in airborne particulate matter (PM2.5).
Application Note 1107: Determination of Anions and Carboxylic Acids in Urban Fine Particles (PM2.5) demonstrates that this new method can determine more analytes relevant to air contamination than either of the two standard methods currently in use. The determination is performed using a high-pressure ion chromatography system, the Thermo Scientific™ Dionex™ ICS-5000+ Reagent-Free™ HPIC™ system, equipped with a...
Leaks at gas chromatography (GC) column connections are a common source of frustration and wasted time in laboratories.
Time is often spent manually tightening connections between columns using a handheld tool – time which could otherwise be spent analyzing results or running more investigations. Preventing GC leaks has become a priority for researchers looking to save time and money while achieving high quality results. GC column connections leak because capillary column ferrules made of graphite polyimide blends loosen after...
VICI’s Pulsed Discharge helium ionization Detector (PDD) extends the detection capabilities of the popular Agilent 6890 and new 7890 GCs.

At the renowned Midsummer House Restaurant in Cambridge, UK the chefs have been experimenting with centrifugal evaporation, using the Genevac Rocket evaporator.
Using the centrifugal evaporation technique, Midsummer House chefs are taking large volumes of liquid and concentrating them down. These concentrates can be used to increase the depth of flavour of sauces or stocks or to create unique flavour combinations. Centrifugal evaporation is predominantly used in analytical laboratories, where the quality of the final product is absolutely vital – just as it is in the kitchen. At Midsummer House, Head Chef Daniel Clifford’s cooking has a...
