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.
A primary example where this is beneficial is Lithium measurement in clinical samples with the increased precision afforded by the use of the Caesium internal reference feature. The M420Cs also benefits from a number of enhancements made recently to all Sherwood’s 420 range of instruments; that now offer a performance specification for precision of < 0.5% CV.
Used as a standalone instrument the M420 Cs 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.
Since introduction of the M420Cs we now stock a 160.0 Na & 8.00 K mmol/l calibration solution, Stock Code 001 56 160; in addition to the 10,000ppm Caesium internal reference solution, Stock Code001 56 601.

Regulated BlueNotes 420 Software
Also new from Sherwood is a “Regulated” version of our M420 BlueNotes software. This latest software package allows the analyst to use the M420Cs Flame Photometer in a way that enables them to work in a manner compliant with 21 CFR Part 11 and enable analysis of up to three elements simultaneously; both with single point or multipoint calibrations.
Regulated features include:
