This is a special liner for aqueous solutions, system suitability requirements were satisfied, and good repeatability was obtained. When using a special liner for aqueous solutions repeatedly, it is recommended that it is replaced after 50 to 100 injections. Typical applications to analyze aqueous solutions: G333: Alcohol Determination of Sanitizer Gel in accordance with USP G315: Analysis of Ethanol in alcoholic beverages Using Nexis GC-2030 Liner volume is approx. 863uL

Fixed needle syringe with super flexible titanium alloy plunger. They are resistant to bending and sliding friction for extended lifetime, even with water soluble samples. Plunger and barrel are machined for an exact fit, so they are not interchangeable with another syringe if either part is damaged. Syringe Volume Min.

Shim-pack MAqC-ODS I reversed-phase columns are packed with a silica gel containing metal and bonded octadecylsilyl group. In addition to the hydrophobic characteristics of the ODS, the metal content also provides cation-exchange effects. This increases the retention of basic compounds. Therefore, this allows use with only a buffer solution as the mobile phase for analyses that previously required using an ion pair reagent and enables using gradient elution. These characteristics are especially beneficial for analyzing water soluble vitamins and pharmaceuticals that contain a large amount of basic compounds. * To use this column efficiently: 1) To increase the retention of basic compounds, please use a buffer solution within the pH 2 to 4 range. 2) In the case of a basic substance tailing, it may be possible to improve the peak shape by increasing the salt concentration of a buffer solution. 3) The elution of basic compounds is faster by increasing the salt concentration, and it is possible to adjust retention by salt concentration.

Includes two cartridges and one holder *1 Note that a delay volume equivalent to the internal volume of the product occurs if the product is installed downstream of the gradient mixer or the confluence of two pumps. * The product service life differs according to analysis conditions, such as the mobile phase used. * Do not use the product when using a mass spectrometer as the detector, as the product may cause bleed noise. * In analysis using an ion-pairing reagent, the ion-pairing reagent may be retained in the product, influencing the retention time and peak shape. * Before connecting the analytical column, be sure to thoroughly clean the flow path with mobile phase (close to the final concentration for gradient analysis). * Note that some impurities may not be removed. * When performing high-pressure analysis exceeding 35 MPa with a UHPLC system, connect the gradient mixer to the Ghost Trap DS-HP with pipe for UHPLC (e.g. 228-53137-97).
