Sample Handling Techniques

After sampling, water samples should be analyzed immediately. If forced to be stored, any water quality parameters require specific treatment to the sample. In addition to treatment with chemicals, preservation of the most common is the cooling at a temperature of 4 ° C during transportation and storage. At this temperature, bekteri activity is inhibited. Samples were delayed measurement and ...

Physical Parameters Air

1) The color of the water In determining the true color, suspended materials that can cause turbidity separated beforehand. Filtration (filtration) aims to eliminate the material suspended in the water without compromising the authenticity of the color of the water. Centrifugation prevent interaction with the color filter material. True colors are not affected by turbidity. Water color can be used ...

Fraction Sand and Dust

Sand fraction dominated by mineral quartz (SiO2) which is highly resistant to weathering processes, while the fraction of the dust is usually derived from mineral feldspar and mica are quickly obsolete, and at the time of weathering would release a number of nutrients, so textured soil dust are generally more fertile than soils sand. From this description shows that the ...
