Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography with the specificity and sensitivity of MS.

Kinetex core-shell HPLC particle technologies provide a high-efficiency, low-pressure solution for laboratories looking to increase productivity and decrease costs without investing in a UHPLC system.

Selecting the most effective source for high-purity gases is a critical issue for laboratory managers. In-house generation of gases offers the following advantages: gases are continually provided; it is not necessary to replace tanks on a periodic basis; less energy is required to supply gas, since tank gas or liquid nitrogen requires distillation of air and transportation of tanks to the final point of use.

The popularity of mass spectrometers (MS) in the food, clinical research and pharmaceutical markets has pushed labs to seek ways to improve the speed of their liquid chromatography (LC), thus increasing the throughput of their MS.

While the fundamental components of a high performance liquid chromatography (HPLC) system—pumps to deliver solvent, an injector, a column for separating the constituents of a sample, a detector and computing software—have remained the same, there continues to be innovations in their design and capabilities.

Recent trends in smaller particle size drives down costs and improves HPLC column and LC/MS column efficiency.

An appropriate HPLC detector has the ability to sense the presence of a compound and send its corresponding electrical signal to a computer data station.

Multiplexing technology enables parallel HPLC systems to synchronize to a single mass spectrometer.

A customer should be aware of the advantages a photo diode array detector brings to their analysis.
