Supplier: Avantor

Ready-to-use pH buffers are manufactured in large lots to stringent specifications and utilise quality control procedures to reduce lot-to-lot variability. You can eliminate the time and expense of preparation and standardisation of solutions, helping streamline high-volume analytical work in applications such as quality control.

Supplier: EHRENSTORFER

This reference material is used as a calibrant for chromatography or any other analytical technique.

Supplier: USP

Organic Standard, N-Nitrosomethylphenidate (NMPH) solution (1 ml (1 mg/ml)) (Methyl 2-(1-nitrosopiperidin-2-yl)-2-phenylacetate)

Supplier: LGC Standards PROMOCHEM

This proficiency testing program (PTP) was specially designed to give analytical laboratories instant validation while measuring viscosity in new and used oils.

Supplier: Restek

Includes all target analytes except the six gases, which are available separately as 502.2 calibration mix #1.

Supplier: LGC Standards PROMOCHEM

Purity estimate obtained from a combination of traditional analytical techniques is 99,3 ± 0,6% mass fraction, (95% coverage interval). The purity estimate by traditional analytical techniques was obtained by subtraction from 100% of total impurities by GC-FID, and Karl Fischer analysis. Supporting evidence is provided by elemental microanalysis and 1H NMR analysis.

Supplier: Restek

Foam generated as purge gas passes through a sample can enter the analytical trap and possibly the GC column. This silica-containing antifoam agent is effective over a wide pH range and will not conflict with chromatography of target analytes.

Supplier: LGC Standards PROMOCHEM

The purity value obtained from a combination of traditional analytical techniques is 99,6 ± 1,4% mass fraction, (95% coverage interval). The purity estimate by traditional analytical techniques was obtained by subtraction from 100% of total impurities by GC-FID, thermogravimetric analysis, Karl Fischer analysis and 1H NMR and also supported by elemental microanalysis.

Supplier: LGC Standards PROMOCHEM

The PTP has been specially designed for analytical laboratories that analyse new and used oils for metals, sulphur, viscosity and particle count.

Supplier: Whatman products (Cytiva)

These cellulose filters are used in qualitative analytical techniques to determine and identify materials.

Supplier: Avantor

The Avantor® ACE® Excel® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.
