24 May / June 2014 New InertSustain LC phases and InertSustainSwift -
Ideal for LC/MS/MS GL Sciences have introduced a new Phenylhexyl phase for the revolutionary InertSustain LC column range, which already includes C18, C8, NH2 and Phenyl. Additionally, in a new development, GL Sciences have introduced InertSustainSwift C18 which is ideal for demanding LC/MS/MS applications. All InertSustain phases are built on a radically new type of silica, in which the surface of the silica has been uniquely modified to produce a new ‘Evolved
Surface’. This Evolved Surface enables precise control of the silica properties, leading to columns that offer superior peak shape and resolution. InertSustain C18 and C8 are robust over the pH range 1 to 10 and are compatible with 100% aqueous mobile phases. InertSustain Phenyl offers unique reversed-phase characteristics that may be critical for resolving some compounds. InertSustain NH2, with optimised aminopropyl bonding, is an ultra performance sugar analysis column and InertSustain Phenylhexyl offers industry leading inertness, lot-to-lot reproducibility and low back pressure.

Rapid and Reliable Determination of Phenolic
Compounds in Soil
Thermo Fisher has developed an efficient and simple high- performance liquid chromatography (HPLC) method with ultraviolet detection for the determination of phenolic compounds (gallic acid, caffeic acid, 4-hydroxybenzoic acid, syringic acid, ferulic acid, salicylic acid, phloroglucinol, cinnamic acid, catechin, quercetin, vanillin, phloridzin, and phloretin) in apple orchard soil. Application Note (AN) 1077: Determination of Phenolic Compounds in Apple Orchard Soil demonstrates that the entire analysis process, including sample preparation and separation for one soil sample, can be accomplished within 80 minutes using this method combined with an accelerated solvent extractor.
Are Your ECD’s Legal ? Leak Testing
ECD’s are required by law to be tested once per year to check for radioactive leaking
ECD Refurbishment
Detectors can be cleaned & refurbished to return stability lost by contamination
Removal of unwanted ECD’s If a detector is no longer required, Ellutia can take ownership of the detector where it will be assesed for re-use or disposal

Phenolic compounds generated from rhizosphere exudation and decomposition of plant material may contribute to replant disease in susceptible plants, including apple trees. Most phenolic substances are water-soluble and aromatic, so reversed-phase HPLC with ultraviolet detection is the analytical technique of choice. Conventional extraction methods for soil samples—such as sonication, hot reflux, soxhlet, and immersion—are time consuming and do not always deliver the desired reproducibility. However, use of the accelerated solvent extractor as described in AN 1077 offers short extraction time, low solvent consumption, high extraction efficiency, excellent reproducibility, and time-saving automation. Thus, when the extraction is combined with the HPLC method, Anchorfruit producers have a rapid and reliable way to monitor the condition of their soil.
