The test is based on the reaction of the cationic polyquat with an anionic polyelectrolyte using Toluidine Blue O as the indicator. The color change is blue to purple. Levels are determined using the drop count method. Range and Sensitivity is 1 drop = 1 ppm Polyquat.

 

This Potassium Test Kit tests for potassium using a turbidity reading tube. Range and sensitivity is 10, 20, 30, 40, 60 ppm K+.

Sodium tetraphenylboron reacts with potassium to form a white precipitate. The turbidity of the solution is proportional to potassium concentration which is measured in a calibrated tube.

 

This kit tests for QAC using the Direct Reading Titrator method. Range and sensitivity is 0-500 ppm/10 ppm Alkyl dimethyl benzyl ammonium chloride.

A masked bromphenol blue indicator is added to the sample and turns green. Sodium tetraphenylboron is added to complex the QAC and the color changes to red. This method is best suited to higher QAC concentrations.

 

This kit tests for QAC using the Direct Reading Titrator method. Range and sensitivity is 0-1,000 ppm/20 ppm, 0-5,000 ppm/100 ppm with dilution.

A masked bromphenol blue indicator is added to the sample and turns green. Sodium tetraphenylboron is added to complex the QAC and the color changes to red. This method is best suited to higher QAC concentrations.

 

This kit tests for Silica using the Octa-Slide 2 Comparator. Range and sensitivity is 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, 10.0 ppm or 5, 10, 20, 30, 40, 60, 80, 100 ppm SiO2.

 

This kit tests for Sodium using the Direct Reading Titrator method. Range and sensitivity is 0-360 ppm Na+

 

This kit tests for Sulfate using the Octa-Slide 2 Comparator. Range and sensitivity is 20, 40, 60, 80, 100, 120, 160, 200 ppm SO42-. Barium forms a precipitate with sulfate. The turbidity formed is measured using comparator standards or a meter.

 

This Sulfide Test kit tests for sulfide using the Octa-Slide 2 Comparator. Range and sensitivity is 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, 15.0, 20.0 ppm S2-.

 

This kit tests for Total Sulfide, Dissolved Sulfide and Hydrogen Sulfide using the drop count method. Range and sensitivity is 1 drop = 1.0 or 0.1 ppm S2- or H2S.

 

This kit tests for Sulfite using the Direct Reading Titrator method. Range and sensitivity is 0-100 ppm/2 ppm SO32-.
