Abstract
A composition and an assay solution for the determination of dissolved borate concentration comprising a catechol dye, a solubilizing agent, and a buffer are described. The composition and assay solution may further comprise a solubilizing agent. The catechol dye acts as a chemical borate sensor. The chemical borate sensor changes its optical properties upon binding to borate. The multivalent cation chelator binds multivalent cations present in a sample being analyzed. The buffer prevents changes in pH. The solubilizing agent aids in solubilizing the catechol dye, multivalent cation chelator, and/or the buffer.

1-95. (canceled)
A method for determining dissolved borate concentration in an aqueous sample, the method comprising:
- contacting an aqueous sample obtained at an oil and gas site with a freeze dried borate assay composition comprising a catechol dye, a multivalent cation chelator, a buffer, and a solubilizing agent, and
- determining the concentration of dissolved borate in the aqueous sample,
- wherein the freeze dried borate assay composition is comprised in a kit comprising a multi-well plate comprising at least a first, second, third, and fourth well,
- wherein the freeze dried borate assay composition is included in the first, second, third, and fourth wells in increasing amounts such that the fourth well includes more freeze dried borate assay composition than the third well, the third well includes more freeze dried borate assay composition than the second well, and the second well includes more freeze dried borate assay composition than the first well, and
- wherein the aqueous sample is contacted with the freeze dried borate assay composition present in each of the first, second, third and fourth wells.
