Signal Uniformity in an Active Two Volume Laser Ablation Cell
Signal Uniformity in an Active Two Volume Laser Ablation Cell
30 Nov 2015Laser ablation as a solid sample introduction technique has always been limited by the sample chamber employed to transport the generated aerosol to a connected ICP-MS. The plasma torch, historically, is intolerant of air in the central channel. Whilst instrumentation is improving apace, isolating the sample from air is still important. Additionally, effective ablation occurs under helium atmosphere. Both these factors mean that an isolated chamber is required. In this study, the positional variation of data quality was assessed using HelEx II cup design installed onto a Teledyne CETAC Technologies LSX-213 G2+ Solid State Laser Ablation System.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Laser AblationICP-MSInductively Coupled Plasma Mass Spectrometry (ICP-MS) is a powerful analytical technique used to determine the concentrations of elements and their isotopes in a variety of samples, including water, soil, and biological tissues. It involves ionizing elements in the samples with extremely high-temperature Argon (Ar) plasma and then using a mass spectrometer to measure the number of ions based on their mass-to-charge ratio (m/z).
