HPLC and LC-MS both separate compounds by liquid chromatography, but they identify what comes off the column in completely different ways. One detects by light absorption, the other by molecular mass. This guide breaks down five critical factors: sensitivity thresholds, selectivity, sample preparation requirements, cost, and consumable specifications. It also explains why most LC-MS problems trace back to low-quality vials and filters, and why certified Type 5.0 vials and 0.22um syringe filters are essential for trace analysis.

In the lab, we often say the mobile phase is the "life line" of the system. Without it, your sample is just sitting in an injector, going nowhere. But how do you choose the right "train" to carry your molecules to the detector? Let’s break it down like we’re chatting over a coffee in the breakroom.

High-Performance Liquid Chromatography (HPLC) and Ultra-Performance Liquid Chromatography (UPLC) are the two pillars of the modern analytical lab. While they share the same fundamental principles, the shift toward UPLC in 2026 is driven by the need for higher resolution, faster throughput, and sustainable "Green Chemistry" practices. By utilizing 5 µm particles in HPLC versus sub-2 µm particles in UPLC, labs can drastically reduce analysis time from 30 minutes down to just 3 minutes.

Expert Environmental Monitoring Guide: An in-depth look at what EPA certification really means, exploring TOC measurement techniques in surface water quality monitoring. This article focuses on the risk of PFAS contamination in plastic bottles and provides laboratories with a professional pre-cleaning consumables solution to achieve low ppb background values.

In the high-stakes world of ultra-trace analysis (ppb/ppt levels), we obsess over column chemistry and mass spec sensitivity, yet we often ignore the very first surface our sample touches: the vial wall. For anyone running UHPLC-MS/MS in proteomics or clinical toxicology, a standard glass vial isn't just a container—it’s a chemical trap that can sabotage your results before the first injection.

Headspace gas chromatography (HS-GC) is a powerful analytical technique for analyzing volatile compounds in a variety of sample matrices, including liquids and ...

This paper illustrates a typical GC‑HS sample vial carousel and details a multi-step cleaning and desorption-preconditioning protocol for high-borosilicate headspace vials. It further analyzes disposable vs. reusable vial models in terms of cost, contamination risk, and operational efficiency, assisting labs in designing an environmentally friendly, reliable, and efficient SOP for sample preparation.
