Sampling – Guidance


Saigon Green E&C has customer support services to collect water, wastewater samples, emissions at source and ambient air. The cost of sampling and shipping will be calculated based on the distance at the sampling location.

Sampling Guidelines

To best serve our customers, please note to send water and wastewater samples as follows:

1.Volume of the sample

Depending on types of sample and parameters to be analyzed, the sample volume can be changed from 1 to 5 liters. However, with basic parameters such as pH, BOD, COD, TSS, Ammonia, Nitrate, Nitrite, TN, Phosphate, TP, etc, sample volume of 2 liters is often enough for analyzing.

2. Bottle containing water and/or wastewater samples

To ensure the quality and condition of the original sample not changed, water and/or wastewater samples should be contained in plastic or glass bottles. Do not contain in a plastic bag because of leakage and change of characteristics.

To avoid affecting the accuracy of analysis methods, the sample should be kept at around 5°C when transferred to the laboratory.

3. Time of analyzing

Normally, the analysis time is from 3 to 4 days for air and gas samples, from 7 to 8 days for water and wastewater samples.

In some cases, depending on request of customers, we can analyze fast in from 1 to 2 days but it depends on types of parameters and numbers of samples.

4.Time of storage sample

Saigon Green Laboratory will store the samples according to guidelines of ISO/IEC 17025:2005 about 5 days after submitted reports to Clients.

5.Time of receiving reports
