Latest App Notes & Case Studies

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.

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.

Polybutadiene (or rubber) is added during polymerisation of styrene to increase the flexibility of polystyrene polymers. It is important to closely monitor the amount of polybutadiene added, so that the flexibility of the polystyrene polymer may be regulated.

Mineral Oil is added to Crystal Polystyrene to increase its flexibility. This process requires a high degree of regulation, as the addition of too much mineral oil will dissolve the polystyrene polymer.

‘Xylene solubles’ is an historically established term denoting the percentage of soluble species in polypropylene homo- and co-polymers. This measure is widely used for product quality control and monitoring physical properties of the polymer during synthesis and processing.
