What is important to determine is if your written SOP or Monograph allows for “Equivalent” columns. If so, the Cogent HyperSphere™ can easily be shown to be “Equivalent”. If your method does not allow for substitutes, you cannot use an equivalent. Most methods written within the last 15 years, allow for substitutes.
