Instant Notes: Analytical Chemistry

Weighing Modern balances can readily weigh samples directly, and masses from several
grams down to a few micrograms can be weighed accurately and quickly. It is
important that the conditions are the same for the initial weighing (crucible,
filter paper) as for the final weighings. Temperature is especially important and
hot samples should neverbe placed directly onto a balance pan.
