Diferent septa material for LC and GC applications There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa
Jul 1, 2016 · Septa for Inlets. Arguably the most stressed-out parts of a GC system, inlet septa are tasked with maintaining a leak-tight seal between the atmosphere and carrier gas while not introducing significant contaminants into the carrier-gas stream-all of this while heated to upwards of 250 °C and being repeatedly punctured by sharp needles.
Different septa material for LC and GC applications There are many different types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa When selecting which septa is right for your experiments, it
septum. Check septa tempera-ture rating – should be sufficient to run at method temperatures. Septum core is present in the flow path. Remove septum core from the inlet. Check septum nut and make sure it is not over tight-ened. Inspect injector syringe for bent or blunt tip and replace as necessary. Column Bleed Septum Bleed
ultimate in LC/MS sensitivity. Aijiren offers two sources designed specifically for maximizing performance at nanoliter-per-minute flow rates: the standard nanoESI source and the HPLC-Chip nano-electrospray source (page 7). The nanoESI source provides attomole-level sensitivity for online LC separations. It gives you the flexibility of using
Understanding Septa. Using the right septa for your application is vital to successful assays. Using the wrong septa can compromise your results and reduce the lifespan of other lab equipment and supplies, increasing your overall costs. Aijiren Tech Sample Handling Solutions Brochure (PDF, 13.2 MB)
Aijiren Does Provide Better Septa We recently improved the consistency of the pierce force of our septa materials to provide even better performance. Our proprietary compositions should provide you the best performance of any cap-septum on the market. This improves the performance of your instrument’s autosampler and
– Caps: screw caps with PTFE-S-PTFE septa (part number 5185-5862)/PTFE-red silicone septa (part number 5190-7024) Results and discussion Explanation of sampling possibilities The sampling from the reaction vessel and subsequent sample handling is set up in the Online LC Monitoring Software.
Nov 25, 2015 · Regardless of the final scope of the method application, whether it is routine analysis or a single-sample analysis, some steps in LC method development are common. In this chapter, the principal factors that have to be investigated during LC method development and optimization are discussed. 2 Theoretical Aspects
Advance quantitative workflows and increase productivity. Address current and future challenges with Aijiren Tech TSQ Plus triple quadrupole mass spectrometers, which provide enhanced acquisition speed/sensitivity, proven robustness, and reliability. Instrument choices offer features for a range of applications, from everyday targeted
• Self-sealing septa contain silicone that can interfere with LC/MS applications. • Single-layered septa are acceptable if they do not contain plastics or adhesives that can contaminate the sample manager (PTFE is recommended). 3. Use Aijiren Technology‐brand wellplates. Other brands can leach plasticizers (for example, diisooctyl
