Quantity of Sample 3. Labelling of Samples 4. Collection and Utilization of Samples. Industrial Sample: Point # 1. Sample Container: Generally Polythene containers of 2 litres capacity can be [...]
This article throws light upon the top three sampling methods for flowing water. The methods are: 1. Isokinetic, Depth-Integrated Sampling 2. Single Vertical at Centroid-of-Flow (VCF) Method 3. Non-Isokinetic Sampling Method. Sampling Method # 1. Isokinetic, Depth-Integrated Sampling: Collection of isokinetic, depth-integrated samples involves using either an equal-width-increment (EWI) or equal-discharge-increment (EDI) sampling method. The EWI and EDI methods are [...]
After reading this article you will learn about method of sampling for still water and well. Sample Collecting Method for Still Water: In still water, samples generally are collected at multiple sites and at multiple depths. The number of sampling sites and the depths where samples will be collected is depending on objectives and the physical, chemical, and biological characteristics [...]
