−The vials were loaded into a sample rack and incubated at 40° C for 72 hours −Final 40° C temperature weight was recorded and the difference from the initial high temperature weight calculated as sample loss in grams. Changes in vial weight representing evaporative sample loss were plotted for each vial in
But I would recomend vial inserts. With inserts you Need less than 10µL volume. My question is I prepare 2 ml of my sample in the glass vial ready for HPLC analysis and the injection volume ...
Orochem Technologies offers vials for HPLC, GC and storage. The volume is from 0.1 mL to 4 mL. Both glass and plastic vials, with or without insert. There are several types of caps and septa. HPLC vials fit into most major brands of HPLC autosamplers.
Although I appreciate that vials and inserts cost money, the cost in terms of time, solvents, cleaning fluids etc. in cleaning these items for re-use, outweighs the cost of purchasing new vials
The syringe needle of an autosampler does not go all the way to the bottom of a vial, and therefore some sample will always remain. This is referred to as the residual volume of the vial. Some vials have a tapered bottom for example, which decreases the residual volume. This can be important if the sample is valuable and of limited amount. .
Vials and closures listed in this section are designed, engineered and manufactured for optimum performance with HPLC and LC/MS applications.
A great deal of energy, money, and time can be spent on sample preparation. The last thing you need is for a sample vial to contribute to contamination resulting in complicated data interpretation or complete reanalysis. By using certified
1.8-425 Standard autosampler vials(11.6*32mm) for GC and HPLC. 2.Available with black or white screw caps with 8-425 thread. 3.Available as closed top screw seals or with centre hole.
Dec 17, 2015 · “The choice of solvents that can dissolve a polymer is typically very limited, compared to small molecules, and limits the type of HPLC method you can use. Also, polymers contain a distribution of chain lengths, which often will result in multiple peaks or a very broad peak during the HPLC separation.

Micro volume vial inserts can be used with screw tops, crimp top, or snap top vials. All conical styles of inserts are offered with the traditional pulled point as well as the improved mandrel point. Pulled point inserts are more economical, but mandrel point inserts provide a more pointed and uniform tip that enables better sample recovery.
