Agilent Technologies’ 1290 Infinity Evaporative Light-Scattering Detector and 1260 Infinity Evaporative Light-Scattering Detector provide up to 9x higher sensitivity, better efficiency and greater reproducibility than other ELSDs.
Chromatography itself can be used as an automated sample preparation procedure for sample purification in drug discovery. Automating solid phase extraction (SPE) is also increasingly useful for rapid sample prep and purification for chromatographic or other analyses.
Solid-phase extraction (SPE) is one of the most common chromatographic processes, and, in recent years, the growth of automated SPE has catapulted its use in laboratories. As a result, SPE systems are becoming more integrated—being made more compatible with liquid chromatography mass spectrometry (LCMS) systems, or combined with LCMS in one system.
New capabilities such as advanced detectors and optics are improving the use of infrared and Raman spectroscopy in the chemical analysis and validation of art objects. The analysis of art objects is conducted for a variety of purposes, with authentication being the most visible.
