increased sensitivity for lowinput labelfree proteomics using orbitrap astral ms μpac neo plus columns

Increased sensitivity for low-input label-free proteomics using the Orbitrap Astral MS and μPAC Neo Plus columns

Instrument Type: LCMS

Goal: To demonstrate peptide and protein identification and measurement precision at low sample input levels using data-independent acquisition (DIA) on the Thermo Scientific™ Orbitrap™ Astral™ Mass Spectrometer with the Thermo Scientific™ Vanquish™ Neo UHPLC System and Thermo Scientific™ μPAC™ Neo Plus 50 cm Analytical Column in direct injection and trap-and-elute workflows.

robust peptide quantitation using tsq certis triple quadrupole mass spectrometer optispray ion source cartridges

Robust peptide quantitation using the TSQ Certis triple quadrupole mass spectrometer and OptiSpray ion source and cartridges

Instrument Type: nanoLCMS

This work demonstrated quantitative targeted peptide analysis using the TSQ Certis triple quadrupole mass spectrometer coupled with the Vanquish Neo UHPLC system. With the OptiSpray ion source and cartridge columns optimized for nano- and capillary flow (<5 µL/min), the platform delivered strong reproducibility, retention time stability, and sensitivity for an 82-peptide plasma biomarker panel.

AN003548 Fast analyses of anions in water with microbore columns using a compact ion chromatography system for reduced eluent use

Instrument Type: IC

Industries are adopting methods to enhance analytical performance while minimizing ecological impact. In ion chromatography, using microbore columns with diameters of 2 mm or less reduces eluent use, cutting hazardous waste and improving throughput.This note highlights rapid anion analysis in water using microbore column, which significantly reduces liquid waste compared to standard bore columns. This method enhances safety and sustainability by minimizing waste production.Both chemical and electrolytic suppression techniques are demonstrated.
