Our History

 

A HistoryOne of LaMotte original test kits of Innovation

In 1919 a young chemist, Frank LaMotte, decided to focus his expertise in the area of pH analysis on specific applications of chemical control. Within a few years, LaMotte's small laboratory in Baltimore, Maryland was manufacturing specialized pH indicators and other analytical reagents for world-wide distribution. The applications section of LaMotte's first major catalog, published in 1930, anticipated many of the areas in which accurate chemical control is indispensable today - boiler water, swimming pools, drinking water, and more.

facilityToday LaMotte Company is located on its own 15-acre industrial park near colonial Chestertown on Maryland's Eastern Shore. The company manufactures analytical reagents, laboratory apparatus, electronic instrumentation, and complete portable test kits for chemical analysis in hundreds of applications.

 

 

Our Methods

 

Visual Colorimetric

A sample is treated with reagent(s) to produce a color reaction. The sample color is then compared against color standards representing known concentrations of the chemical being tested.

Electronic

Electronic methods generally use a special electrode for measuring a specific test factor. An electrode is immersed into a sample and an amplified current or voltage is produced and translated into a digital readout.

Electronic colorimeters measure the amount of light which travels through the reacted sample, and convert the measurement to a reading as ppm, absorbance or %T. In addition to colorimeters, LaMotte manufactures instruments to test pH, TDS/conductivity, dissolved oxygen, and turbidity.

Titrimetric

In a titrimetric method, titrating solution (or titrant) is added to a treated sample until a color change occurs. The volume of titrant required to reach this endpoint reaction is proportional to the concentration of the chemical being used.
