Laboratory Services

 

Laboratory and Production division of ENPHO has been providing its analytical services on water, air, soil and food quality since its inception in 1990. ENPHO Laboratory has been accredited under the NEPLAS criteria (based on ISO 17025) by Nepal Bureau of Standards and Metrology, Government of Nepal. The main objective of this Laboratory is to contribute to ENPHO’s overall mission of transforming Nepalese society into a healthy and eco-friendly society through its services. This Laboratory has also established itself as an important platform for research and development activities in water, sanitation and environment sectors.

Laboratory division of ENPHO is well equipped with sophisticated instruments like atomic absorption spectrophotometer (AAS), ultra violet (UV) spectrophotometer, double distillation unit, four digital electronic balance, pH meter, electrical conductivity meters, automatic digestion and distillation units, and various types of oven, incubator, and furnace for physical and chemical parameter analysis. Furthermore, it is equipped with several filtration units (Millipore and Del Agua units), different range of incubators, autoclave and refrigerator for microbiological analysis.

Besides analysis, this unit of ENPHO has developed various types of water testing kits like water quality field test kit, arsenic test kit, free residual chlorine (FRC kit), Coliform Presence/Absence (P/A) vial, and water disinfecting chlorine solutions like Piyush, Piyush Plus and body belt incubator.

The laboratory and production division has also conducted different projects in the year 2072-2073. ENPHO Lab tested the drinking water quality in households of Kathmandu, Bhaktapur and Lalitpur districts using ENPHO water test kits. The findings were disseminated through ENPHO booth in WASH campaign for 25th year celebration of ENPHO. Besides, water quality testing was also conducted in seven different earthquake affected districts in terms of microbial parameters. Also, ENPHO also organized bacteriological water quality tests at street food vendors and findings were later presented at ENPHO in 25-year celebration program. ENPHO also conducted project on “Study on efficiency of ceramic candle filters” in association with Water Resources Management Programme (WARM-P), HELVETAS Swiss Inter cooperation. Other projects carried out includes, microbial water quality study in  mid and far western regions of Nepal in support of HELVETAS and groundwater quality study of Kathmandu valley in post-earthquake scenario. Additionally, the division has also been involved in various water quality testing and treatment trainings.

The new instruments introduced in the lab during FY 2012/2013 are:

Advanced UV spectrometer with in-built software:

This instrument makes spectrometric analysis more systematized and less prone to human error as it generates results on its own through its software, thus making result generation more efficient and accurate. The software can also be tailored according to our analytical requirements.

Automatic Distillation Unit:

The new distillation unit is a well proven and tested model that supports automatic rapid distillation with high reliability, user-friendliness and safety. The features such as time chemical (Sodium hydroxide) addition using time controlled pump, automatic steam generator, automatic monitoring of the temperature increase timer controlled distillation, simple and manual change of sample tubes and protective door makes this instrument more user-friendly and efficient.

2

Digestion Unit:

This advanced digestion unit can be used to digest upto 12 samples at a time (6 more than the one previously used) hence facilitating faster analysis of the samples. In this unit, the temperature is homogenously distributed in this unit which minimizes the error in the digestion process and hence in the analysis.
