The Model 420Cs is the latest addition to Sherwood Scientific Ltd.’s Flame Photometer range. Based on the established M420, the Model 420Cs offers improved performance and flexibility.

Where the Model 420Cs comes into its own is with the addition of a Caesium filter, enabling use of a Caesium internal reference as an alternative to the Lithium reference channel offered on Sherwood Dual Channel models up to now. This additional feature, gives operators the ability to choose the internal reference element based on the sample matrices or to adapt existing procedures originally developed for discontinued instrumentation such as the IL 943 Flame Photometer.

Used as a standalone instrument the M420Cs allows the operator to simultaneous measure up to two of three available elements (Sodium, Potassium and/or Lithium) and a choice of Caesium or Lithium as the internal reference.
