Jun 20, 2016 · Normal-Phase HPLC The column is filled with tiny silica particles, and a non-polar solvent, for example, hexane. A typical column has an internal diameter of 4.6 mm or smaller and a length of 150 to 250 mm. Non-polar compounds in the mixture will pass more quickly through the column, as polar compounds will stick longer to the polar silica than
HPLC can be applied to just about any sample, such as pharmaceuticals, environmental, forensic, food, nutraceuticals, and industrial chemicals. In HPLC, separation is achieved through the distribution of the analytes between a stationary phase packed in a column and a liquid mobile phase that is pumped through the column.

Waters columns are therefore standard equipment in every laboratory. The innovative columns lead to significant time and cost savings per sample in analysis processes, and thus lead to better quality of laboratory results. Choose from over 4,500 HPLC columns from Waters by narrowing down your search using the drop-down menu on the left.
stability. The ability to inject large sample amounts (up to 1–2 ml per injection) makes HPLC a very sensitive analysis technique. HPLC and the nondestructive detection tech-niques also enable the collection of fractions for further analysis. In addition, modern sample preparation tech-niques such as solid-phase extraction and supercritical fluid

Sample Vials Wide selection of vials, including HPLC Certified vials (tested by HPLC for cleanliness) and LCMS Certified vials (tested for total ion count and presence of clusters in the high mass range). These are the cleanest vials in the industry.
6. Preparation of a sample for analytical HPLC 1) Prepare a ~50 µM solution using HPLC solvent or other appropriate solvent 2) If the sample or solvents have not be previously HPLC chromatographed, filter the sample solution through a 0.2 um filter. You may not inject unfiltered samples. 3) Use volatile buffers ONLY.

Feb 16, 2013 · Quality Water for HPLC Analysis. Water for HPLC is used in most mobile phases and also in sample preparation. Water has been rightly termed as a ‘Universal Solvent’ because it dissolves most substances, is easily available and has non-toxic nature but at the same time ordinary tap water is not used for laboratory applications because of its potential for interference due to presence of
