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.

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 assay is comprised in a kit comprising a multi-well plate having the freeze dried assay dispensed into the wells of the multi-well plate.
