[labnetwork] HMDS lifetime in YES oven

[Zhichao Wang]

Dear Lab Network,

I was wondering how long the lifetime is for the HMDS in the YES oven. On
the note from the YES's website, it says " If the HMDS is more than a year
old, it should probably be replaced". I would assume the "year" here starts
from the HMDS manufactured date, which is the shelf life for a brand new
bottle of HMDS. Do you guys have experience on using the HMDS for extended
time (like 6+ months) after the expiration date? Please let me know your
thoughts and suggestions. Many thanks!


Best,
Chao
