Services

The Analytical Laboratory of the Geological Survey and Mines Bureau has pioneered in the techniques of silicate analysis in Sri Lanka. We have been providing quality analytical services to industry and scientific research ventures for over five decades.

The laboratory provides accurate and reliable chemical analyses of rocks, minerals, ores, ground water, surface waters, industrial effluents and other miscellaneous materials using internationally accepted techniques and standards at highly competitive rates.

Main functions:

Basic and advanced chemical analysis in the following fields:

•Mineral Industry – Raw Materials Testing
•Water Quality Testing
•Geochemical Mapping and Research
•Environmental Quality Assessment

This has been a training centre for university undergraduates, postgraduates and scientific officers from relevant public sector departments.

Methodology and instrumentation

Sample preparation

•Pulverizing by contamination free tungsten carbide mills
•Traditional Silicate Digestion methods/ A modern micro wave digestion
•Preparation of pellets for X-ray Fluorescence Analysis using a Katanax Fluxer

Analysis

Atomic Absorption Spectrophotometer with flame, furnace and hydride generation techniques to determine more than 25 major, minor and trace elements.

Inductively Coupled Plasma Atomic Emission Spectrophotometer to determine minor, trace and some rare earth elements.

Recently installed Wavelength Dispersive X-Ray Fluorescence Spectrometer to determine major minor and trace elements without sample destruction.

UV-Visible Spectrophotometer & the Ion analyzer to analyse anions such as phosphates , fluorides , chlorides, nitrates etc.

Other available equipment includes furnaces, pH/ dissolved oxygen meters, conductivity/ salinity/TDS meters etc.
