Hall Analytical - Latest News
In our latest news section we plan to give you regular updates regarding particular types of analysis that we have been undertaking.
Hall Analytical Investing in the Future - October 2011
Hall Analytical has continued to invest in a variety of new scientific instrumentation. This has been done as part of the ongoing commitment to ensure we give our clients both the range and quality of data that they require to address their analytical challenges. All systems have full IQ/OQ validation.
We have purchased a Karl Fischer Coulometer to provide accurate water content measurements. The equipment, complete with an oven will allow fast and precise water determinations from samples.
A new FTIR complete with an ATR arrived at the end of August. The new system will allow rapid raw material identification through to low level analysis of formulated products. This analytical technique will complement our other systems, especially in assisting to identify unknown compounds.
Recently installed is a Xevo G2 Q-TOF LCMS(MS) system. This will provide more accurate and sensitive results and expand our LCMS(MS) capability.
Hall Analytical continues to make a major contribution to polyurethane foam safety - March 2011
Consumer product safety is becoming an increasingly important concern in within the chemical industry. One of the areas that Hall Analytical has made a major contribution in both developing tests and advising certification groups is that of polyurethane foams.
Hall started work in this area in early 2000 and much of the research has been adopted into standard tests. Hall has continually lowered detection levels and improved the reliability and reproducibility of the testing.
As such Hall Analytical is one of only a few laboratories which are approved for doing such testing. We not only test foams to ensure compliance to the Certipur testing requirements but we will also provide information should a foam not pass the stringent requirements.
Hall Analytical has been at the forefront of polyurethane testing for many years and the following item recently appeared in the American Polyurethane Foam Association February newsletter, click the links for further information

|
There are now 40 CertiPUR-US registered products, from 13 manufacturers with products from 2 more manufacturers pending. See complete list here: Certipur Products. A recent surge in CertiPUR-US hangtag orders from retailers provides evidence of a successful value-added voluntary testing, analysis and certification program. The certification program received a great feature story in Furniture/Today on the opening day of the October Furniture Market. |
Nitrosamines - November 2010
Nitrosamines are suspected carcinogens and can be potentially found in such samples as rubber products, cosmetics, cured meats and other types of consumer products.
Whilst GC-NPD and even chemiluminescence have been used to determine nitrosamine levels, both methods are limited in either relative response differences (up to a factor of 30) or in their ability to have a further confirmatory factor, such as molecular weight.
We have developed a GCMS method which allows us to determine the presence of nitrosamines down to the 1ppb level. Closely relating relative response factors allow an excellent linear calibration curve to be established. Using a nitrosamine internal standard and an extraction method based on AOAC 987.05 the samples can be analysed by selected ion monitoring GCMS.
If you require further information on any of these topics, please don't hesitate to get in touch.
