When you operate ion chromatograph or mass spectrometry detection, you find some impurity peak issues, maybe because it’s caused by the test matter or the sensitivity.
It’s quietly probably cased by the sample vial. In this situation, we need use some specials to solve this issue.
The ordinary chromatography is used to detect the organic, but we may detect some sodium ions or calcium ions in the ion chromatograph. These kind of ions exist in the glass material that is the sample vial we use often.
Therefore, we recommend to use plastic sample vials in the ion chromatograph, because we can exclude the interference of the glass ion and eliminate impurity peaks. But if the glass vials are necessary in your experiment, what can you do now? So what about our Welch medium borosilicate vials? Compared with the low borosilicate vials, the medium borosilicate has more advantages in the ion chromatography.
|DA1005||2mL Transparent 9-425 medium borosilicate vial with Scale. 100pcs/pk.|
|DA1111||2mL Amber Glass 12×32mm Flat Base 9-425 Screw Thread Vial with Label, 100pcs/pk.|
|DA1411||2mL Transparent PP Wide Open 9-425 Screw Vial with Scale. 100pcs/pk.|
If you compare with the ordinary liquid chromatography and find there are still some impurity peaks in the mass spectrometry detection, it’s also caused by the high sensitivity.
Regarding the mass spectrometry, it needs less interference of impurity, however the ordinary vial can’t make it.
So we Welch technology still has special product for helping you, that is our high clean vials. These vials are additionally and specially processed during production, so with the high cleaning, it can reach high standard in the test.
Avoiding the pollution, we combine packaging between the cover and the vial. So you’d better using it after unpacking it as soon as possible. If you need high standard in your experiment, maybe you can try this product.
