Dpd powder white for first time - all previous orders arrived blue grey

[Silver_2000]

Just received my reagent replacement. Been testing w tfp reagents for 7-8 years and purchase new almost every year. This year the vial of powder has dessicant and contents are snow white. Never seen that before

I'm guessing it's normal just new to me

Totally normal.
I think it oxidizeds over time and that is reflected in the color difference.

This year the vial of powder has dessicant and contents are snow white.

Nate started including it inside the tub. Mine stayed white all sesson last year where previously it didn't for long. It was still good, but chunky and grey.

I also keep the tub in a small Rubbermaid container with a couple silica packs. Twice or so a year I buy something that happens to come with them and I swap them out.
