● Preparation of food samples.● Analysis different kinds of foods using analytical techniques like: chromatographic, gas chromatography, precipitation titration, flame and flame-less atomic absorption.● Conducting Artificial color, Sudan (for benzene compounds), Tobacco (for nicotine),Salt and Aflatoxin (for toxic fungal compounds), and Heavy metals tests.

Conducting quantitative analytical techniques for building materials include:● Testing content of chloride by using back-titration method and sulphate by using the precipitation method for (sand, soil,road base and sub-base) samples.● Testing water contents of alkalinity, pH, TDS, sulphate and chloride using auto-titration and spectroscopic methods
