Abstract Management of microbiological food safety is largely based on good design of processes, products and procedures. Finished product testing may be considered as a control measure at the end of the production process. However, testing gives only very limited information on the safety status of a food. If a hazardous organism is found it [Read More...]
Everyone likes to have a safety net, and scientists are no different. This month I will be discussing internal standards and how we can use them not only to improve the quality of our data, but also give us some ‘wiggle room’ when it comes to variation in sample preparation. Internal standards are widely used [Read More...]
For many food products, validating and verifying a process sounds like a simple task if the product has been made for years and is considered very safe. In many of these cases, one immediately thinks about the time and temperature of a cook step. In other cases, one might think there is no process because [Read More...]
A new mass spectrometry imaging protocol allows the analysis of metabolites like adenosine monophosphate from formalin-fixed paraffin-embedded (FFPE) tissue, shown here as background. (Credit: Helmholtz Zentrum München) The metabolic composition of tissues can be determined—in one day—in fixed-tissue samples, using a newly developed mass spectrometry imaging protocol. Using relatively small amounts of material, [Read More...]
Shimadzu Scientific Instruments (SSI) announces the opening of the Shimadzu Laboratory for Advanced Applied and Analytical Chemistry at the University of Wisconsin-Milwaukee (UWM). The new 2,000-square-foot laboratory and office suite is a hub for research across the entire UWM campus, as well as a classroom for teaching the theory and practice of mass spectrometry. The [Read More...]
The space is no bigger than a good-sized office break room. On beige counters along the walls and on an island in the center sit off-white rectangular boxes that could be copiers or printers. But the several hundred thousand dollars of highly sensitive scientific equipment in this room — and others like it — will be [Read More...]
ANN ARBOR, MI, JULY 4, 2016 -- Endress+Hauser is expanding its manufacturing facility for Raman analyzers. Wholly-owned subsidiary Kaiser Optical Systems is investing $8.6 million US dollars to develop the Ann Arbor, Mich. location, which will more than double in size. "The new facility will be the core of our future Raman-spectroscopic analyzer manufacturing," said Tim [Read More...]
Dan Anglin, a Marine Corps veteran and chairman of the Colorado Cannabis Chamber of Commerce, is the founder and chief executive officer of Americanna, an infused products business in Colorado with a heavy focus on regulatory compliance, consistent dosing and product safety. The company was the very first to implement the THC stamp, a requirement [Read More...]
While analytical laboratories may still rely to some extent on trial-and-error approaches, there is agreement that this is increasingly less effective as systems become more complex. Regulatory bodies are putting increasing pressure on pharmaceutical companies to incorporate Quality by Design (QbD) approaches throughout the drug development process. QbD is defined in the ICH Q8 guideline [Read More...]
With a price tag of $1 million, many schools can't afford the latest spectrometry equipment to help students conduct experiments, like determining the composition of a polymer or detecting the presence of cocaine in a hair sample. But that may soon change, thanks to the first virtual mass spectrometry system—an interactive, Web-based educational device developed [Read More...]
