Calibration standards, stock solutions, matrix spikes; if a reference standard can be made, ERA will be happy to prepare it for you and supply a comprehensive Certificate of Analysis. While the cost of custom standards depends on the complexity of your requirements, the cost for most simple standards is reasonable. The final cost is dependent upon the materials, time, complexity of the standards, and extent of analytical validation required. In every case, you will receive a fixed price quotation based upon your project requirements and you can count on ERA to deliver what you need, when you need it. To discuss your Custom Standards needs, call and speak with an ERA Customer Service Representative at 800-372-0122 or 303-431-8454.
