A wide choice of tests is available, for routine quantitative analysis in different applications, designed for use with WTW spectrophotometers and photometers. The test is automatically recognised by the laboratory instruments (via a barcoding system) and results are displayed in the appropriate units. Due to the different photometer optics, one test may yield different measuring ranges in different instruments; LED photometers may have smaller measuring ranges for the same test.

Supplier: Ahlstrom-Munksjö

Ahlstrom-Munksjö’s qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions. High Purity hardened filter papers grades 1288 to 1291 are also produced from cellulose with an alpha content of nearly 100% resulting in an ash content of <0,1%.

Avantor® ACE® C18-PFP phase utilises a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

DMEM Low Glucose was the original modification of Basal Medium Eagle (BME) used to grow mouse embryonic cells. DMEM, Low Glucose is suitable for the culturing of many immortalised cell lines from humans, monkeys, hamsters, rats, mice, chicken and fish. DMEM contains four times more amino acids, vitamins and other supplementary components than Basal Medium Eagle (BME), the base media from which DMEM was derived. As DMEM contains no growth-promoting agents or proteins, supplementation with FBS is recommended for optimal performance.

Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent in the Bond Elut™ range. It is the most popular SPE sorbent because of its extremely retentive nature for non-polar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.

Step 2: Dispersive SPE cleanup
Select the dispersive SPE kit suited to the type of food being analysed and the method you are following. In this step, an aliquot of the sample extract from step one (see QuEChERS extraction kits) is added to a 2 or 15 ml centrifuge tube containing a small amount of SPE sorbent and MgSO₄. The sorbent will pull out interfering matrix materials from the sample, while the MgSO₄ helps remove excess water and improve analyte partitioning.

Avantor® ACE® CN-ES combines CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited. Extra phase stability and increased column lifetime is provided by an extended alkyl chain spacer between the silica surface and cyano group. Avantor® ACE® CN-ES is suitable for both reversed phase and normal phase separations.

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.
