Rapid analysis of nine antioxidants in cooking oil (采用UHPLC法快速分析食用油中的九种抗氧化剂)

Instrument Type: UHPLC

In this paper, by using small size packing column, A UHPLC method was established for the simultaneous determination of propyl gallate (PG), 2,4, 5-trihydroxybutanone (THBP), tert-butylhydroquinone (TBHQ), demethyldihydroguaiacic acid (NDGA), tert-butylp-hydroxyanisole (BHA), 2, 6-ditert-butyl-4-hydroxymethyl phenol (IONox-10) in edible oil 0), octyl gallate (OG), 2, 6-di-tert-butylp-methyl phenol (BHT), dodecyl gallate (DG)9 antioxidant solutions. The method has a short analysis time, and can complete the separation of nine antioxidants in 11 minutes.

Vanquish Neo UHPLC system sets new performance standards for single-shot nanoLCMS bottom-up proteomics

Instrument Type: nanoLCMS

Demonstrate the superior performance of the Thermo Scientific™ Vanquish™ Neo, next-generation low-flow UHPLC system, for nanoLCMS bottom-up proteome profiling when coupled to a Thermo Scientific™ Orbitrap Exploris™ 480 mass spectrometer using the 75 μm I.D. × 75 cm Thermo Scientific™ EASY-Spray™ PepMap Nep column. Demonstrate system versatility and potential for new levels of proteomic depth coverage through the coupling of two 75 cm long nano columns.

Increase sensitivity in UHPLC-MS analysis by minimizing post-column dispersion

Instrument Type: LCMS

Reduce post-column dispersion with small ID capillaries for fast gradient UHPLC-MS methods using sub-2 μm particle next-generation columns

New Double Barrel ESI Source and Novel Tandem NanoLC-MS for 24/7 Proteome Profiling with near 100% MS Utilization​

Instrument Type: nanoLCMS

The developed tandem nanoLC-MS platform which allows routine 24/7 operation with close to 100% MS utilization comprises: (i) tandem Thermo Scientific™ UltiMate™ 3000 RSLCnano system; (ii) Double Barrel Column Oven (Sonation GmbH) installed onto the Thermo Scientific™ Nanospray Flex Ion Source; (iii) Thermo Scientific™ Q Exactive™ HF-X Hybrid Quadrupole-Orbitrap™ Mass Spectrometer; (iv) Optimized intelligent method script for automated switching between columns during the method execution

Novel Determination of Bromate in Aqueous Samples using 2-mm-Columns and UV-Detection, ISO 11206

Instrument Type: IC

This proof of concept application determines trace bromate in aqueous samples by ISO 11206. The second scope of this work was to apply modern 2-mm-column technology to the derivatization approach described in the ISO method as well as in Thermo Fisher Scientific Technical Note 116. Both those documents use 4-mm-columns. Using 2 mm columns reduced eluent consumption and hence waste.
