The Challenge:   A real time, reliable and coast efficient analytical instruments for detecting inorganic, organic and bacteriological contaminants in water.

There are two classes of inorganic contaminants that fall into two classes: metals, including oxides of selenium, lead and mercury, among others, and inorganic species, including chlorides, sulfates and nitrates, among others.  Organic contaminants include pesticides and industrial organic chemicals.  Some common waterborne bacteriological contaminants include gastroenteritis, typhoid, dysentery, hepatitis, giardiasis, Cryptosporidiosis, E. coli and other pathogens.

In the United States, as in many other countries, drinking water is regulated, and there are strict regulations about maximum contaminant levels (MCL).  Water suppliers must ensure that regulated levels are not exceeded.

The dominant analytical method for the transition metals is the inductively coupled plasma mass spectrometer.  For inorganic species, ion chromatography plays a leading role.  The major method for organics is gas chromatography, along with mass spectrophotometer detectors.  There has been considerable progress in the use of high performance liquid chromatography systems combined with UV detection and current trend is seems to be moving toward use of mass spectrophotometer detection.

These methodologies and techniques are built into a variety of analytical instruments now in use to analyze an array of inorganic, organic and bacteriological contaminants in water.  All of them have few common flows: they cannot be used in real-time, they require contact with water, most of them require consumables, have large sizes, very complicated to use and very expensive.

The Solution:   As part of our company mission is a commitment to develop cost effective tools that can monitor water supplies 24 × 7 without human supervision to enable public health laboratories, food companies, and water authorities to protect consumers from numerous water contaminants.

NWMM-200 is our answer to that challenge.  This instrument is a scalable tool that could in real-time with no direct contact monitor numerous parameters of water from its salinity and pH to detecting organic and non-organic contaminants including harmful chemicals, high levels of lead and mercury and presence of dangerous bacteria and viruses.  NWMM-100 could be used in various settings from government utility laboratories, wastewater treatment plants and privately owned commercial laboratories that have full range of scientific instruments to numerous end-users that need to monitor water quality in real time in field setting.
