Parameters

MANTECH is a leading manufacturer of automated titration and multi-parameter analysis systems. We can deliver analysis systems that perform the following functions: (click the links to view method abstracts)

We have purchased a MANTECH system to automate our suite of pH, Conductivity and Turbidity analysis. From industry feedback we knew that this suite is notoriously difficult to automate and the MANTECH system presented a new and viable solution to the problem. Camlab, the UK representatives have helped us from the very outset with the financial justification and there on with the development of our methods and engineering support. The staff, from product specialist to the engineers at Camlab have understood the constraints of our methodologies and have worked with us as a partnership to deliver the high performance we need.
I worked with three multi-parameter systems running applications such as pH, conductivity and alkalinity. It was wonderful being able to set up my run and then move on to other tasks around the lab. One of the systems often ran for ten hours straight (approximately 750 samples). The MANTECH systems were easy to use and very durable.
MANTECH instruments used by ALS have proven to be robust analytical solutions, generating accurate and precise results with a low per sample operating cost.
The support was excellent from all vendors but the software and hardware support teams for the MANTECH PC-Titrate system were local and are marketed and supported by the same company. The precision was superior on the PC-Titrate system as was the multi-valve cleaning system, which included more titrants, and purging of titrant lines. In conclusion the PC-Titrate system met our needs most closely and was the best long-term choice for our solutions analysis.

Frequently Asked Questions

Titration uses a solution of known concentration to determine the concentration of an unknown solution. The titrant (the solution with a known concentration) is added from a buret to a known quantity of the analyte (the solution with an unknown concentration) until the reaction is complete. Knowing the volume of titrant added allows the concentration of the unknown solution to be determined.

The potential of hydrogen (pH) is a measure of hydrogen ion (H+) concentration. Solutions with a high concentration of H+ ions have a low pH (acidic). Solutions with a low concentration of H+ ions have a high pH (alkaline). Read MANTECH’s pH method abstract here.

Conductivity, also known as electrical conductivity, is used to measure the concentration of dissolved solids which have been ionized in a polar solution such as water. Read MANTECH’s conductivity method abstract here.

Oxidation-reduction potential (ORP), also known as redox potential, refers to the capacity of a solution to oxidize (accept electrons) or reduce (donate electrons). ORP sensors work by measuring the voltage across a circuit formed between the indicator and reference electrodes. When an ORP electrode is placed in a solution containing oxidizing or reducing agents, electrons are transferred back and forth on the measuring surface, generating an electrical potential. Common applications for the ORP method include monitoring water chlorination processes for water disinfection, distinguishing between oxidizers and reducers present in wastewater, and metal screening. Read MANTECH’s redox potential method abstract here.

Ammonia is a colourless gas that is soluble in water and has a distinctive odour. It is a mild environmental hazard because of its toxicity and ability to remain active in the environment. Direct measurement of ammonia using a calibrated ion selective electrode (ISE) is a quick, accurate and precise way to easily determine ammonia levels. Read MANTECH’s ammonia method abstract here.

‘Hardness’ is defined as the total concentration of alkaline earth ions (Ca2+, Mg2+, Sr2+ and Ba2+) in water. The Ca2+ and Mg2+ ions dominate the alkaline earth ions. Therefore, one can refer to total hardness as the total concentration of the Ca2+ and Mg2+ ions in solution. Hardness is expressed as mg CaCO3/L water sample (ppm CaCO3). Read MANTECH’s hardness method abstract here.

Nitrates (NO3) are formed from the two most common elements on earth, nitrogen and oxygen. Their presence in soils comes from nitrogen-fixing bacteria in the soil, decay of organic matter, industrial effluents, human sewage, and livestock manure. Nitrates are a serious problem since they do not evaporate, and hence remain dissolved and accumulate in the groundwater. Read MANTECH’s nitrate method abstract here.

There are two types of salinity, absolute salinity and practical salinity. Absolute salinity is a ratio between the mass of dissolved material in seawater and the mass of the seawater. Practical salinity is the ratio of the electrical conductivity of a seawater sample to that of a standard potassium chloride (KCl) solution at the same temperature and pressure. Read MANTECH’s salinity method abstract here.

Turbidity is defined as the amount of suspended particles in a solution, measured in nephelometric turbidity units (NTU). It is used as a general indicator of the quality of water, along with colour and odour. The US EPA has a maximum contaminant level (MCL) of 5 NTU for drinking and wastewaters. Read MANTECH’s turbidity method abstract here.

Alkalinity refers to the capability of water to neutralize acid, also known as an expression of buffering capacity. A buffer is a solution to which an acid can be added without changing the concentration of available H+ ions (without changing the pH) appreciably. In other words, a buffer absorbs the excess H+ ions and protects the water body from fluctuations in pH. Read MANTECH’s alkalinity method abstract here.

The main compounds of alkalinity are: hydroxides (OH), carbonates (CO32-), and bicarbonates (HCO3).  The alkalinity, or buffering capacity, of a solution depends on the absorption of positively charged hydrogen ions by negatively charged bicarbonate and carbonate molecules.  When bicarbonate and carbonate molecules absorb hydrogen ions, there is a shift in equilibrium without a significant shift in pH.  A sample with high buffering capacity will have high bicarbonate and/or carbonate content, and a greater resistance to changes in pH.  For more information on MANTECH’s method for automated alkalinity measurement and how the species of alkalinity are calculated, download the pdf.
