HPLC columns have a different length varying from 30 mm to 250 mm and their particle size or porosity from 3µ to 5µ. These factors affect the analysis of sample, therefore, these are considered important during the HPLC analytical method development. Columns are selected according to the nature of the compound to be analyzed and the mobile phase.
Not having the right consumables can bring your project or lab to a halt. Not all vials are the same, some syringes just do not work, and certain fittings just leak. Do not allow your productivity to be slowed. Ensure you have products that are compatible with your Shimadzu instrumentation.
Waters also offers a selection of glass sample vials and plastic sample vials that fit most manufacturers’ instruments. Two of the most popular uses are as HPLC vials and GC vials. These chromatography vials can be used as sample storage vials by adding a solid caps with liner.

High-performance liquid chromatography (HPLC) is an important analytical method commonly used to separate and quantify components of liquid samples. In this technique, a solution (first phase) is pumped through a column that contains a packing of small porous particles with a second phase bound to the surface.

mers of 2-PP, 3-phenylphenol (3-PP) and 4-phenylphenol (4-PP), and no me-thod has been reported for assay of 3-PP or 4-PP. While the previous method employing HPLC-UV after derivatization with 4-fluoro-7-nitro-2,1,3,-benzox- adiazole was simple, the reagent is expensive and the system was not applicable
How to use : 1. Insert a Cosmospin sample reservoir into a Cosmospin sample collection tube. 2. Add a sample into the Cosmopsin sample reservoir. 3. Close the sample collection tube cap and centrifuge. 4. ImpuritiesRemove the sample reservoir and collect the filtered sample in the sample collection tube. 5. Analyze the filtered sample by HPLC
Vials and closures listed in this section are designed, engineered and manufactured for optimum performance with HPLC and LC/MS applications.
A great deal of energy, money, and time can be spent on sample preparation. The last thing you need is for a sample vial to contribute to contamination resulting in complicated data interpretation or complete reanalysis. By using certified
HPLC Chromatography Vial, 2mL CLEAR Glass vial with Writing Area, Flat Base w/ graduations, 9-425 Open Top Ribbed Screw Cap with 9mm White PTFE/Red Silicone Septa 1mm Thick, w/ intergrated 0.2mL MIRCO-INSERT, Vial size: 12 x 32 mm, 100/pk CV5700
recommended for HPLC use. Ultra pure HPLC water (18M Ω resistivity) is generated by passing deionized water through an ion exchange bed. Modern water purification instruments use this mechanism to produce water of suitable quality in high volumes. Alternately, HPLC grade water can be purchased from solvent suppliers. I-2. Buffers
