HPLC Sample Preparation | Life Science Research | Sartorius
HPLC sample preparationClean samples = clean results. HPLC is one of the most common high-precision analytical methods. Its primary objective: deliver reproducible and specific results. A sample needs to be optimally prepared so it can be injected directly onto an HPLC column. To accomplish this, your sample not only needs to be dissolved in
Laboratory Filtration & Purification Devices| Sartorius
Optimize your HPLC sample preparation for higher analytical accuracy. Your HPLC results can only be as good as the quality of your sample preparation. Using Sartorius products to prepare samples for HPLC prevents the usual problems from occurring: No blockage of your HPLC column. Higher sensitivity of your HPLC column. Higher accuracy.

Collecting Samples for Laboratory Testing | Lab Tests Online
Jul 19, 2021 · Some samples are collected by simply running a swab over the affected area. Procedures of this type can be performed in a clinic, in your doctor’s office, or at the hospital bedside. The sample may be sent to a laboratory for analysis (although a few tests can provide in-office results in just a few minutes).
LC-MS Sample Preparation | Thermo Fisher Scientific - US
The sample’s physical and chemical characteristics are critical to determining how it is digested and prepared for liquid chromatography. Filtration is often applied to samples that contain particulates such as undissolved salts, and many laboratories use hydrophobic or hydrophilic PTFE filters to remove interfering materials and fine particles.

An Introduction to High Performance Liquid Chromatography
High Performance Liquid Chromatography, or HPLC, is the most common analytical separation tool and is used in many aspects of drug manufacture and research. HPLC is used for: 1. Qualitative and quantitative analysis of unknown mixtures – determining what is there, and how much. 2. Separation of mixtures for later analysis –preparative HPLC.
