Problem solved. The format in Region settings should be set to "English (United States)", nothing else. As a result, the Decimal symbol under Numbers in Additional settings becomes a point (Anglo-Saxon decimalization) instead of a comma (Western European…
Hi Helene,
Thank you for contacting Cell Analysis Technical Support. Sodium bicarbonate cannot be used because it is a buffering agent with a very high pKa and, unless incubated in a CO2 incubator, will raise the pH of the assay medium to well above…
Great. The 219 and 502 are quite high. Make sure that the extractor lens insulator is clean, the extractor pin isn't touching the body, the brown extractor lens connector wire is connected well and not crimped, and that the transferline tip seal ceramic…
Hi AVEdsell,
Site prep clearly states that system MUST be vented, this is a snippet from the TQ site Prep Guide about Venting. I do not know waht MS you have but this is common for all :
Bonjour Fabrice,
Juste pour ajouter a l'information que Kristen a deja donne:
Si vous selectionne la langue comme Francais, vous pouvez trouver le manuel. La description, de mon cote, a l'air d'etre en anglais, mais si vous cliquer sur le lien…
Hello lperry ,
For Cool on Column inlets, the septum and the inserts types are dependent on the column size. It is quite possible that either the septum, the insert, or both, are not matching the column size.
Are the needles getting bent too? Does…
Hello Samehalsharawy ,
Can you please elaborate on the statement we uninstalled the cylinder expecting the flow to come down to zero but it didn't. It stayed at 50?
If no physical tank is connected to the GC, the GC gas connections are capped…
