Aug 1, 2019 · This installment is the second of a series of four white papers on high-performance liquid chromatography (HPLC) modules focusing on pumps, autosamplers, ultraviolet (UV) detectors, and
the analysis. Several septa are available with either slits or a starburst pattern pre-cut into them. These cuts provide a secure seal, but allow easy penetration by the autosampler needle. The various types of septa, their properties and incompatibilities are listed in the table below. Septa Use with Avoid Resealability Temperature Limit Barrier
Jul 31, 2020 · Needle Gauge: A bigger needle gauge can need more force to get through non-pre-slit septa, which could cause damage to the septa or sample contamination. A pre-slit septum might be the best choice in this situation. Injection Frequency: A pre-slit septa may be more appropriate for applications requiring repeated injections since it can lessen
The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone/PTFE or PTFE/natural red rubber. Our screw vials and vial screw caps are designed for both HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels
Dec 21, 2021 · Having the preslit septa helps ensure reproducibly in sample draw from the vial. The preslit septa are compatible with different autosampler injector needle materials like PEEK and metal-tipped. You may not want to use a preslit septa if your sample diluent is extremely volatile or if samples are heated.
The Aijiren 2 mL MS 32 mm analyzed vial kit is perfect fit for HPLC and GC instrument platforms across a wide variety of applications including pharmaceutical, environmental, energy and fuels and forensics. This product is only available to U.S. Domestic Customers. For research use only,. Compare this item.
Alliance HT HPLC Systems. This vial delivers maximum sample capacity (~1.5 mL) with minimum residual volume. The 9 mm cap makes it ideal for use with Aijiren HPLC and GC Systems. Choosing the level of certified vial should be based on the concentration of analyte. Concentration of analytes is often tied closely with the detection source used.
Mar 17, 2009 · New PRE-CUT Septa for HPLC Applications. Mar 17 2009. In HPLC often slitted or cross-slitted Silicone/PTFE Septa are used, in order to offer a penetration aid for the fairly thick and dull needles used in the HPLC instruments. While the instrument needle requires the slitted septa, the user may run into the risk of concentration changes due to
An autosampler works by aspirating and injecting a precise sample volume into the mobile phase stream. Using an autosampler reduces manual labor and improves injection precision and accuracy compared to manual sample injection, an absolute priority for a quantitative HPLC analysis.
Autosampler vials are designed to carry your sample matrices into your GC or HPLC instrument via the autosampler. Aijiren's autosampler vials include a wide range of HPLC vials and GC vials designed and optimized to work with Aijiren autosamplers & HPLC, GC platforms.
Jul 1, 2016 · In the filled-loop mode, the rotor is placed in the load position, as shown in Figure 1a. In this configuration, the pump output is connected directly to the column through one of the rotor passages; the sample loop connects the sample inlet to waste. Sample is introduced manually from a syringe or in an autosampler from an automated syringe.
