Since 1900, Thomas Scientific has been providing the latest in laboratory supplies, laboratory equipment, laboratory instruments, laboratory chemicals and laboratory safety to the science community.
evaporative sample loss and septum dislodging during the use of standard 9 mm chromatography vials and closures was conducted. Sample losses were measured for both overtightened vials and for vials perceived to be optimally tightened and these were compared to losses from new vials designed to provide a definite sealing point.

We now offer 19 different polymer-based HPLC columns for reversed phase, anion exchange, cation exchange and ion exclusion separations. Two silica-based C8 and C18 columns are available for reversed phase separations. Choosing the Right HPLC Column Before you select an HPLC column to separate your sample please check the Hamilton Company
1-4mL Autosampler Vials For HPLC、UPLC、GC Appcation: Aijiren has been involved in the design and manufacture of vials, caps and seals for chromatography for almost as long as chromatography has been used as an automatic analytical technique.
1. User manually loads sample into the injector using a syringe 2. and then turns the handle to inject sample into the flowing mobile phase which transports the sample into the beginning (head) of the column, which is at high pressure Autosampler: 1. User loads vials filled with sample solution into the autosampler tray (100 samples)

HPLC: High Pressure Liquid Chromatography 2013 Chem 413 Introduction Chromatography can be described as a mass transfer process involving adsorption using a nonpolar stationary phase and a mobile polar phase titrating through the column. The active component of the column, the sorbent or the stationary phase, is typically a granular
Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible identification errors are eliminated.
It can be molded into a molding product with complex shape, accurate size and metal or non-metal inserts at one time. Therefore, this method has strong adaptability and high production efficiency. 10-425 2ml HPLC vials
different for each type of containers (glass versus PP vials) and confirmed that the vial adsorption phenomenon was one of fact ors that compromised the reliability of anal ytical results obtained. This article describes the adsorption behavior of newly developed low-adsorption HPLC vials with respect to basic compounds and peptides.

The most important feature of the silica used in column manufacturing is low metal impurities content. If metal impurities are present, there is possibility of peak deterioration (tailing, low peak height etc.) which results in lower sample recoveries.
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.
The vials, septa and closures available in the Thermo Fisher Scientifi c Chromatography product range are manufactured using highly sophisticated technology and premium quality raw materials. Products are manufactured and tested in accordance with strict quality standards ensuring consistent quality is
