Testing method for residual organic compounds in a liquid sample

A system for measuring the concentration of at least one anti-corrosion saturated and/or unsaturated aliphatic nitrogen containing organic compound in a water sample from a thermal power system or other steam water cycle, the system for measuring comprising:

• a pump for pumping the water sample through the system fro measuring;
• an ion exchange column in fluid communication with the pump;
• a first vacuum degasser channel in fluid communication with the ion exchange column;
• and
• a spectrophotometer in fluid communication with the ion exchange column via the first vacuum degasser channel, the spectrophotometer configured to transmit light having a wavelength in the UV spectrum into the water sample and measure the absorption/transmission of the light in the UV Spectrum by the at least one saturated and/or unsaturated aliphatic nitrogen containing organic compound in the water sample.

A system for measuring the concentration of an organic compound in a liquid sample, the system comprising:

• a pump for pumping the liquid sample through the system;
• a vacuum degasser unit having a first vacuum degasser channel and a second vacuum degasser channel, the first vacuum degasser channel in fluid communication with the pump;
• a strong acid cation ion exchange column in fluid communication between the first vacuum degasser channel and the second vacuum degasser channel;
• and
• a spectrophotometer in fluid communication with the second vacuum degasser channel, the spectrophotometer configured to transmit light having a wavelength of 190 nanometers to 310 nanometers into the liquid sample and measure the absorption/transmission of the light by the organic compound in the liquid sample.
