Feb 5, 2015 · Using vials that are not fit for purpose can affect quality of analysis in various ways. Non-uniform bottom thickness which can damage needles and cause inconsistent sample draw. Sample evaporation and loss can be caused by poor sealing, and misaligned, dislodged or cored septa can result in sample contamination and damage to autosampler injectors.

• 100 sample autosampler for minimal protein loss and automated data collection. Required Supplies • Sample filters, 0.02-0.2 μm filters (recommended) • Autosampler vials (provided by the CMI) • Analytical SEC Column: o A range of analytical SEC columns can be used including silica and agarose columns

Sep 17, 2015 · Peptide storage in a standard “basic” sample buffer (BB) for LC-MS/MS analysis (2% ACN, 0.1%TFA) led to the substantial binding of peptide materia to the vial for the two lower concentrations. Importantly, at the lowest 30 fmol μL −1 concentration it was most of the peptide material that stuck to the vial leading to many peptide complete

Founded in 2007, Zhejiang Aijiren, Inc. specialized in chromatography consumables, such as autosampler vial for HPLC, headspace vial, GC vials, micro inserts, septa and caps, syringe filter, etc, covers more than 10000 square meters, and has clean workshop more than 2000 square meters. 100, 000 class cleaning room;

Ensure sample integrity with Gold Grade inert vials Aijiren Tech Chromacol GOLD-Grade vials provide increased productivity, confidence in results and reduce cost of analysis. These vials are manufactured from a higher grade of glass with the lowest levels of alkaline materials to deliver the lowest surface activity possible.

It’s easy to think of vials as simple, inexpensive components that don’t affect your results. However, substandard vials, caps, and septa can lead to sample loss, contamination, and damaged autosampler needles. Aijiren understands that vials are a critical part of your analytical workflow—no less important than the column or the instrument.

Jun 7, 2013 · We examined suppression capabilities of six different sample injection solutions and seven types of autosampler vial surfaces using a model sample (tryptic digest of six proteins, 1 fmol per protein).

Provides adequate venting to prevent vacuum formation in sample vial, delivering excellent sample-draw reproducibility Eliminates coring from bottom draw needles Good resealing capabilities Recommended for multiple injections Working temperature range from -40 ˚C to 200 ˚C PE Septumless Same advantages as PTFE Cap Vial Septum 3 2 1

Aijiren polypropylene vials, or PP vials, are available in fill volumes starting at 250 µL. The complete range of 2 mL plastic sample vials have the same external dimensions as our standard wide-opening 2 mL glass vials and are fully compatible with our full range of screw caps, snap caps and crimp caps. 2 mL plastic vials (sometimes known as polypropylene HPLC vials or 1 mL plastic vials

Aijiren sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial.

Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. Different bottle mouth designs meet different actual needs. The 1.5ml 11mm crimp-top autosampler vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use.

Filter vials are a fast, economical, and environmentally conscience way to filter samples. The single, convenient and easy-to-use unit replaces the combination of syringe filters, syringes, autosampler vials, septa, and caps. With Captiva filter vials, there are fewer touchpoints in the sample journey, meaning fewer chances for contamination.
