Model 420Cs Industrial Dual Channel Flame Photometer with Li & Cs Ref

The M420Cs is Sherwood's newest addition to the Flame Photometer product line. Evolved from the well-established M420, the M420Cs provides a precision (%CV) ≤0.5, now achievable with all new dual channel models: i.e. the M420 &M425. Unique to the M420Cs, is addition of a Caesium reference channel. This enables the analyst to work with Caesium or Lithium as an internal reference.

The M420Cs' additional internal reference option provides greater flexibility; operators have the ability to choose the internal reference element based on the sample matrix considerations or existing procedures developed for discontinued instrumentation such as the IL 943 Flame Photometer.

A practical example where the Caesium option is beneficial is analysis of Lithium in clinical samples while still being ableto benefit from the improved precision achieved by use of an internal reference.

Features:

• On board firmware with blanking, calibration and sample routines.
• Simultaneous measurement of two out of three elements: Sodium, Potassium and/or Lithium.
• Linearised Sodium response over the expected clinical Sodium concentration range (1 in 200 sample dilution).
• Internal reference facility for improved precision.
• Automatic flame ignition and optimisation.
• Safety features including optical flame and low air pressure detection for fuel gas shut off.
• Two digital displays for calibration and analysis data of each channel; analogue outputs for use with chart recorders and some on-line analysers.
• A 'no tools' maintenance approach allowing easy access to mixing chamber and burner assembly.
• RS232 for data output to a serial printer.
