4 Puddle and Cover
5 Swirl or Zig-Zag Pattern, No Cover
Standard application used for heat sensitive samples if sample burns when using
the puddle and spread technique.
If the sample is a water-based liquid or solvent-based chemical, use a pipette to
puddle the sample onto the pad(s). Cover the sample with an additional pad. A
sufficient number of pads should be used to ensure that liquid samples do not drip
onto the floor of the instrument cavity.
