Improve detection limits and analysis reproducibility for peptide and protein quantification with these low adsorption plates and vials. Designed for LC-MS analysis in autosampler ready formats with low residual volumes in 700 µL 96-well plate and 300 µL sample vial formats.

2. Filling sample vials. Figure 1 shows the recommended fill volumes for sample vials of: • 1 mL for the 2 mL vial • 50 µL for the 100µL vial The air space in the vial is necessary to avoid forming a vacuum when sample is withdrawn. This could affect reproducibility.

Level 3 - vial, cap, and septa kits. EPA Certified Screw Vial & Cap Kits. HPLC & GC Certified Screw Vial & Cap Kits for 2 mL Samples. Precleaned, EPA certified assembled kits; includes 40 mL screw vials and 24 mm. open top screw caps. 0.3 and 1.5 mL screw top vial-cap kits for analysis of small sample volumes.

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.

vaporized sample. Important, especially for polar solvents with large vapor volumes. If vapor volume of sample exceeds liner volume, samples may back up (backflash) into carrier gas supply lines, causing ghost peaks and reproducibility problems in chromatography. Aijiren liners are primarily 2mm or 4mm in inner diameter

Jun 2, 2017 · Choose good quality vials, and when filling, only fill to the shoulder of the vial, leaving a small headspace above the sample liquid. This prevents vacuum formation and cavitation when aspirating the sample from the vial, which can lead to irreproducible sample volumes being drawn into the autosampler syringe.

Autosampler Vials Aijiren Tech™ 9mm Clear Glass Screw Thread Vials Nearly eliminate septa push-through and improve sealing with vials built with the innovative Advanced Vial Closure System (AVCS).

Oct 30, 2007 · Also, what brand/model HPLC and/or autosampler, e.g. Aijiren model #1050 or whatever. We use 5ul injections or less for our assays (autosamplers), and get way better repeatability than that. Manual injection will not produce as accurate results, but should meet your criteria if done correctly with a 5ul loop.

The autosampler component of a HPLC system is used to increase sample throughput, improve the precision of injections, and allow for unattended operation. Its main components are a needle or syringe, a metering device to measure sample volume, and a sample loop. There is also a valve used to control the hydraulic path of the eluent.

sample capacity of the AS 1310 autosampler. System Control All necessary electronics are on board the sampling module. Both AI 1310 and AS 1310 can be controlled through the data system set-up menu. System Setup Easy self-aligning, slide-in installation does not require any turret/syringe adjustment over the injector or the sample vial. RoHS
