Welcome to "Sample Workflow"!

Lecture 1: Applying STXM in multi-modal environmental science investigations: from sample preparation to publication

The first video in this Canvas Module is a workshop presentation by Dr. Sarick Matzen. In Sarick's 30 minute lecture, he provides an overview of field work, sample preservation, sample preparation, and overall analytical workflow for natural samples.

Demonstration 1: Using a portable glove bag in the field

In this set of short videos, Dr. Sarick Matzen demonstrates how use portable gloves bags for sample preservation during oceanographic expeditions and field work in remote locations.

(1) Setting up portable glove bag

(2) Putting on glovebag gloves

(3) Taking off glovebag gloves

(4) Loading items into glovebag

(5) Inflating and purging glovebag

(6) Packing samples

(7) Sealing mylar bags
