Coronavirus information

In response to the COVID-19 global pandemic, the University of Alaska Anchorage has taken steps to protect the health and safety of our campus community. Visit the University of Alaska Coronavirus Information website to learn how UAA and the university system are responding to this situation. Find links to communications, policy guidance, resources and information about the university's community restrictions, which apply to all faculty, staff and students. The UAA Student Health and Counseling Center remains open at this time to serve UAA students. For information about COVID-19 symptoms and current health recommendations, visit the CDC website and the Alaska Department of Health and Social Services.


Sample Preparation

Preparation is a very important step in most analytical techniques. Most techniques are not responsive to a target analyte in its in-situ form, and often the results are distorted by interfering species. Good sample preparation is key to obtaining good data.

Among many techniques, sample preparation may involve:

  • Dissolution
  • Extraction
  • Reaction with some chemical species
  • Digestion
  • Filtration
  • Dilution
  • Sub-sampling
  • Chelation

Fortunately, all of this can be done at ASET and we provide training and consultation for free to the UAA community!

ASET maintains an array of specialized equipment for sample preparation that can be used to analyze a diverse array of matrices. These include: tissue, plasma, soil, sediment, and water. Please contact us with questions if you don’t see what you’re looking for.

ASET contains the following to assist with sample preparation:

Accelerated Solvent Extraction (ASE) (Dionex ASE200 and ASE350) This automated system provides rapid extractions of both major constituents and trace contaminates found in tissue and soil samples. Typical methods run on the ASE require 10 times less solvent than classical methods and can be completed much more quickly.

ASE

Microwave Digestion System (Milestone ETHOZ EZ) This digestion system is equipped with Teflon vessels and uses automated temperature and pressure programs for digestion. It is used for total digestion and extractions of rock, tissue and plant material.
