ULTRACHECK Blind QC Standards

Ultra Scientific Ultra Check1ULTRAcheck® is a series of blind quality control standards used to check whether or not your analytical system is in control. ULTRAcheck® samples are designed to mimic real-world samples for specific EPA methods, and are run as blind samples. The analytical data generated using the method is then compared to the true values supplied with the ULTRAcheck® standard. Agreement between the data generated for ULTRAcheck® used as a blind sample and the true values of the ULTRAcheck® standard indicates that your analytical system is in control.

 Use ULTRAcheck® on a Regular Basis to:

  • Train Personnel
  • Establish and maintain EPA method proficiency
  • Verify analytical system accuracy and precision
  • Prepare for next state or EPA environmental audit

ULTRAcheck® true values are provided in a separate, sealed envelope. The envelope can be sent to another site, upon your request. Data obtained using the ULTRAcheck® blind sample can be immediately compared against the true values supplied. Complete instructions are included with each sample.

Know Your System is in Control

The analytical system is shown to be in control when the data generated for the ULTRAcheck® blind sample falls within the advisory range listed on the ULTRAcheck® certificate of analysis. If the data generated for the ULTRAcheck® blind sample does not fall within the advisory range, immediate corrective action can be taken prior to proficiency failure and loss of accreditation.
