Agilent, 6310001200, Partitioned tubes, pyrolytically coated, 10/pk

The partitioned graphite furnace tubes are consumable atomization components for compatible graphite furnace atomic absorption spectroscopy systems. A pyrolytic coating provides a defined graphite surface that supports controlled thermal behavior during repeated sample drying, pyrolysis and atomization cycles. The partitioned geometry is intended for the corresponding furnace arrangement and should not be treated as interchangeable with a standard unpartitioned tube. Graphite furnace performance depends on consistent tube positioning, clean sample introduction and carefully selected temperature programs. During installation, inspect the tube for cracks, coating damage or contamination and seat it using the instrument's designated tube-handling procedure. Use an appropriate furnace method for the sample matrix and analyte, with blanks and calibration standards to monitor analytical performance. Replace tubes when deterioration, high background or irregular peak shapes compromise validated measurements. Protect unused graphite tubes from dust, fingerprints and mechanical damage. The package contains ten tubes for instrument maintenance and analytical consumable replenishment.
