Latest App Notes & Case Studies

Inorganic cations are significant indicators of the quality of drinking waters and their suitability for human consumption. They have important physiological effects and they alter the palatability of water.

Boilers used in power stations hold ultra pure water, the purity of that water needs to be determined by highly sensitive techniques. Ion Chromatography is a technique which offers high sensitivity.

Carbohydrates are important constituents in both food and drink. They are frequently added to improve the flavour and palatability to the consumer. Non-alcoholic drinks, especially carbonated soft drinks, can have as much as 10.7 g of sugars added to them. Although there are specific carbohydrate columns for the separation of mixtures of sugars these can be expensive.

It normally takes some 40 minutes to analyse a 16 component mixture of polyaromatic hydrocarbons (PAHs) or polynuclear aromatic hydrocarbons (PNAs). With the aid of the WaveQuest UV/Visible HPLC detector, this analysis is greatly speeded up to 4 minutes and can now be performed on a routine basis.

Although wax was originally treated as a waste product by the oil refining industry, it is now widely used in manufacturing because of its specific mechanical and physical properties. As oil content is one significant parameter in the composition of wax that affects its physical properties, it needs to be measured routinely.

Biobanking is becoming a central element in the study of patient genetic data and clinical application of genetic research. Until recently, collections of DNA samples have tended to be fairly small and localized with varied sample containers that were unsuitable for an increasing throughput and automated system use.

With the storage of biological samples such as DNA, protein, blood fractions and viable cells becoming commonplace. The need to store them at lower temperatures has resulted in reading challenges for traditional rack readers.

The ion trap is a powerful tool for metabolism studies, due to the MSn capability for the identification of metabolites and structure elucidation of unknown peaks. The TurboDDS™ software on the Varian 500-MS LC Ion Trap eliminates the need to do multiple runs in order to identify metabolites. Once the expected m/z of a metabolite is entered into the method, the 500-MS will automatically look for this m/z and when found, will immediately trigger an MSn experiment.

Massively parallel DNA sequencing technologies are of pivotal importance in genome biology and medicine, as they can potentially enable comprehensive and systematic evaluation of genetic variation. Currently, these sequencing technologies are geared toward sequencing whole genomes.
