Oil spectrometer disk electrode rod electrode;

Using high-purity graphite (spectral purity), it has the characteristics of high strength, high density, high purity, high chemical stability, dense and uniform structure, high temperature resistance, and high conductivity

Comprehensive analysis of disk electrode and rod electrode in spectrometer

Sample excitation and transmission

The disk electrode rotates to transport the sample in the oil box to the gap between it and the rod electrode. Then, under the action of oscillating arc, the two jointly generate instantaneous high temperature, causing the oil sample to evaporate and dissociate into gaseous atoms, which are excited to form characteristic spectral lines of the elements. The combination of rod electrode and disk electrode forms an arc discharge zone, ensuring that the sample is fully excited, and the design of immersing it in the oil box helps to stabilize the oil sample transportation.

Material Properties

Using high-purity graphite (spectral grade), it has high strength, high density, high temperature resistance, and chemical stability. The uniformity of porosity is good, which can reduce background noise and improve detection accuracy.

Purity and porosity

The impurity content directly affects the background signal interference, and the porosity affects the stability of the arc temperature, thereby determining the repeatability and accuracy of the detection results.

size effect

The outer diameter of the disk electrode determines the sample carrying capacity, while the inner diameter affects the rotation rate and oil sample transport efficiency; The length and diameter of the rod electrode need to be matched with the equipment to ensure consistency in the excitation gap.

Mainly used for element analysis of lubricating oil, hydraulic oil and other oils, detecting wear metals (such as iron, copper, aluminum), pollutants (silicon, sodium) and additive components, suitable for oil condition monitoring of aircraft engines, marine gearboxes and other equipment.

consumable replacement

Both disk electrodes and rod electrodes are consumables that need to be replaced regularly (such as 500 disk electrodes per box and 100 rod electrodes per pack) to avoid residue interference with testing.

Usage Specifications

The new batch of electrodes needs to be calibrated and compensated, and residual oil samples should be cleaned after use; When storing, it should be kept dry to avoid graphite oxidation.

Rotating Disc Electrode Technology (RDE): Combined with a photoelectric direct reading spectrometer, it achieves rapid detection of multiple elements and has become one of the mainstream methods for oil analysis.
