-How is the sampling method of plumbing drinking water for microbial testing?
First, sterilize the tap with alcohol and allow the water to drain out of the tube for a while, then completely fill in a liter of sterilized container and put it in the immediate vicinity of the ice and transfer it to the laboratory quickly.
-How long after the sample is delivered to the laboratory, the test results will be ready?
Typically, laboratory results are prepared after a week, depending on the type of sample and the need or lack of preparation can be less or more.
-What are the minimum parameters needed for drinking water?
The minimum parameters are total coli form, focal coli form, pH and TDS
-How much should sample size be for heavy metal analysis?
The sample size depends on the type of sample and the method of measurement required and the desired element, but in general, for solid samples, about 100 grams, and for liquid samples, about 200 mL of the sample is required.
-Is there any measurable element at ppm in the plant samples such as Pb and Cd?
