Atomic Absorption Spectrometry is an analytical technique used in quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. This is used for elemental analysis of Manganese, Iron, Copper, Zinc, Barium, Cadmium, Lead, Nickel, Selenium, Arsenic, and more.
Gravimetric Analysis
Gravimetric analysis is a technique wherein the amount of an analyte can be determined through the measurement of mass. Gravimetric analysis depends on comparing the masses of two compounds containing the analyte. It involves isolation of an ion in a solution by a precipitation reaction, filtering, washing the precipitate free of contaminants, conversion of the precipitate to a product of known composition, then weighing the precipitate, and determining the difference in mass. From the mass and known composition of the precipitate, the amount of the original ion can be determined.
Volumetric Analysis
Volumetric analysis also known as titrimetric analysis is an analytical technique that involves measurement of volume from a solution with known concentration which is used to determine the concentration of the analyte.
Colorimetric Analysis (UV-Vis)
Colorimetric analysis is an analytical technique that uses color changes in comparing solutions to determine the concentration of analyte. It utilizes a special type of spectrometer known as UV Vis spectrophotometer. It is used to measure the intensity of light by absorption or transmission which is proportional to the concentration of the colored solution.
Thermal Analysis Techniques (TAT101)
Thermal Analysis Techniques (TAT101) course is a lecture-discussion of the four thermal analysis techniques in characterizing polymers. These are the Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA) and Thermo-Mechanical Analysis (TMA).

Water Analysis Techniques (WAT101)
Water Analysis Techniques (WAT101) will discuss an overview of the clean water act and other administrative orders by the Department of Environment and Natural Resources (DENR) regarding water quality criteria and approved methods of analysis. It will tackle proper sample collection technique, water sample storage, transportation, and preservation per water quality parameters as approved by the Philippines’ standards.
Water Analysis Techniques (WAT101) will also discuss the principles of the analysis of wastewater in pH, dissolved oxygen, biological oxygen demand, chemical oxygen demand, color, total suspended solids, oil and grease, inorganic phosphates, nitrates, and ammonia, using the approved methods set by the DENR. It will also discuss the different water quality parameters’ correlation with each other and their effects on the ecology of our water systems.
