Analytical & Research Services

CAS-IC Analytical Services Laboratory

The Analytical Service Laboratory (ASL) was established in November 28, 1985 during the 982nd meeting of the University of the Philippines Board of Regents as an extension arm of the Institute of Chemistry, University of the Philippines Los Baños (UPLB). ASL provides training and consultation to researchers in the academic, government and private institutions and chemical analysis of water, food, feeds, soil, sediment, and biological sample at a minimal cost.

This laboratory provides the clients with the following services:

  1. Proximate analysis of food and feed samples
  2. Water quality analysis of of various water samples (ground water, surface water, treated and untreated water samples, and industrial effluents)
  3. Mineral analysis of various samples using Atomic Absorption Spectroscopy (AAS)
  4. Physico-chemical and carbohydrate analyses of various samples and quality evaluation of oils
  5. Analysis of soil and sediment samples
  6. Crude extraction of plant material; concentration and phytochemical screening of crude extract
