FAT UB Integrated Laboratory

FAT UB Integrated Laboratory


Integrated Laboratory of the Faculty of Agricultural Technology, Universitas Brawijaya Malang, is a laboratory service facility for integrated education, research, and community service programs.

Functions and Roles

To become an integrated laboratory with international standard in serving testing, research, and community service to support superior research activities of the FTP UB Integrated Laboratory.

FTP UB Integrated Laboratory serves Testing and Analysis of Samples from students/lecturers/researchers from within FTP UB and from outside FTP UB.

Equipment and Facilities

Equipment :

  • UV-Vis

An analytical instrument used to measure the absorbance power of a liquid that has a chromophore group to a certain wavelength of light.

  • GCMS

This instrument is used for the process of analyzing volatile organic chemical compounds through two tools that are combined into one (GC tandem MSD). Samples containing volatile compounds were injected into the GC system and then the separation process was carried out in the column based on the nature of the polarity. After being eluted from the GC system, each compound that has been separated will enter the MS system to then be fragmented with a certain ionization energy.

  • HPLC

This instrument is used to separate molecules of components that are soluble in a carrier solution and are heat sensitive in a solution, such as vitamins, antibiotics, drug active ingredients, small amounts of drug or food additives, proteins, various types of sugars, waste components, and etc.

  • Spray Dryer

A device used to produce dry powder from a liquid by drying it quickly with hot gas. Spray dryer uses a liquid flow, in this operation, there is a separation between the solvent or suspension as a solid and the solvent into a vapor.

FTP UB Integrated Laboratory as a research and service laboratory has several facilities for these activities, namely:

  • Research Laboratory Room
  • Testing/Analysis Laboratory
  • Atomic Absorption Spectrophotometer (AAS)

Atomic Absorption Spectrophotometer (AAS) is a tool for analyzing metal and mineral concentrations in samples. The basic principle of AAS is to measure the absorption of light by evaporated metal atoms at certain wavelengths. This process involves the emission of light by metal atoms excited by an external energy source, such as a flame or arc lamp. AAS is used for analysis of elements such as Fe, Pb, Cu, Zn, Hg, As and many other metal and mineral elements.

  • Differential Thermal Gravimetric Analyzer (DTGA)

    Differential Thermal Gravimetric Analyzer (DTGA) is a laboratory tool that combines Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) into one instrument. DTGA is used to analyze the thermal properties of materials, such as decomposition, oxidation and phase changes, by measuring changes in temperature and sample weight over time or temperature.

    DTGA works by comparing the sample temperature with a reference temperature that does not react during heating. When a sample undergoes a thermal change, such as decomposition or a chemical reaction, the temperature difference between the sample and the reference is recorded. Meanwhile, the weight of the sample is also measured simultaneously, so that information about mass changes during the thermal reaction can be obtained.

    DTGA is frequently used in a variety of fields, including chemistry, materials, and the environment, for the characterization of materials and further understanding of their thermal properties.

  • TIR – ATR (Fourier Transform Infrared Attenuated Total Reflectance) 

    FTIR-ATR (Fourier Transform Infrared Attenuated Total Reflectance) is an infrared spectroscopy analysis technique used to analyze solid and liquid samples. To identify functional groups  in samples based on the absorption pattern of infrared light by chemical bonds in molecules. This technique is often used in various fields, including chemistry, biology, pharmaceuticals, and materials,

    The way FTIR ATR works involves placing a sample on a sending crystal with high infrared conductive or transparent capabilities, such as germanium, zinc selenide, or diamond. Infrared light is then emitted into the sample through the sending crystal. Most of the light is reflected back into the sending crystal, and a small portion is absorbed by the sample. This absorption pattern is then measured and analyzed to identify the chemical components in the sample.
