Carbon Sulfur Analyzer Analytical Process Common Failures and Solutions

High Frequency Furnace Plate current not in normal range (normal 200~600mA)

Failure causes and solutions: Plate current is less than 200mA, indicating that the sample weighing amount is too small. Low combustion power; non-ferromagnetic sample. It is possible to increase the sample weighing amount, or increase the amount of accelerator.

Carbon Sulphur Analyser Software Release Program not Normal

Failure causes and solutions:

(1) Peak shape trailing phenomenon, indicating that the sample weighing more, the content is too high difficult to release, and low power.

(2) Release double peaks, indicating that the high content of the sample weighing too much.

(3) The release time is more than 20", indicating that the sample is difficult to melt, insufficient oxygen blowing.

(4) Release time more than 50", high content, trailing; large crucible blank; low analyzed flow gas volume.

Notes: the role of several accelerators: enhance the induction effect of the analytical system (Cu, Sn); reduce the melting point of the sample material, melt fully (Iron); carbon, sulfur solubility of carbon and sulfur release (Tungsten, Iron), there is a dilution effect, can increase the melting point of the sample material to help release fully.

High Frequency Furnace Melt Shape with Bubbles

Failure causes and solutions: indicating that the melt temperature is low (improper choice of accelerator, etc.); power is low. Available to choose the appropriate accelerator or reduce the sample weighing volume.

Repeatability of Analysis Results is Poor

Failure causes and solutions:

(1) If the content is too high and exceeds the linear range, the sample weighing amount can be reduced.

(2) Low content, unstable blank. The crucible should be processed in oxygen-rich atmosphere; use high purity oxygen; prolong some blowing time appropriately; use accelerator with high purity.

(3) Bad sample preparation. The sample can be cleaned; re-sampling; baking; standardized sampling.

(4) The sample is uneven. It can take a large average; do more parallel analysis or ask the delivery unit to re-sample.

(5) The quality of the accelerator, the blank is not stable, should choose the blank stable.

(6) The instrument is not used for a long time, which will cause the detector, electronic components moisture or other reasons. Using standard samples to do test checks, and maintenance personnel to cooperate with the inspection or maintenance and repair.
