Mar 22, 2020 · 1. Types of Autosampler Vial Closures . HPLC / GC Vials are available in three closure types; crimp, snap and screw cap. The closures have advantages and disadvantages. Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation.
Better peak shape of gaseous samples. Less activity for small injections of active compounds. Disadvantages. Very small internal volume is easy to overload with normal injection volumes. Outer Diameter (OD) /. Splitless Liner. Example: AG0-8499. Large OD / Splitless. Function: Fits tightly inside the inlet; limits sample contact with inlet

mdi PVDF membrane Syringe filters type SYVG incorporate a PVDF membrane with a binder free borosilicate Microglassfiber prefilter in a polypropylene housing. All mdi filters are color coded for ease of identification and offer a number of unique performance advantages: HPLC Certified for low
The PVDF Syringe Filter produced by Aijiren is made of high-quality raw materials. The filter membrane is very suitable for sample preparation and reagent filtration. Aijiren believes that the PVDF Syringe Filter can be integrated with water-based reagents, and the hydrophilicity ensures that the PVDF Syringe Filter can filter water-based
chromatographers need to use HPLC vials which have inserts in them so that small samples can be reproducibly injected into an HPLC system. Using 0.2 µm filters, we obtained consistent filtration of 100 µL samples. For all the types of vials tested, greater than 70% recovery was obtained when filtering 4 or more samples at the same time (Table 1).
