Inductively Coupled Plasma Emission SpectrometerPerformance Characteristics

Safe and reliable solid-state RF power supply

The RF power supply used in the instrument has small size, high output efficiency, stable output power, and various safety protection functions such as water, gas, and overload, greatly improving the safety of the instrument and reducing its failure rate.

High degree of instrument automation

The automation level of the instrument, except for the power switch, is completed by software for all operations. Intelligent software that can provide real-time feedback and information prompts for various operations.

Fully automatic ignition and matching technology

The software can automatically ignite with one click, and all parameter settings changes are automatically completed. Combined with excellent automatic matching technology, the ignition success rate is high and the operation is simple.

Intelligent flame monitoring function

The instrument is equipped with a sensitive fiber optic sensor, which can monitor the working condition of the flame in real time while the instrument is in operation. In case of abnormal flameout, the instrument can be automatically shut down.

High precision airflow control system

The plasma gas, auxiliary gas, and carrier gas used in the operation of the instrument are all controlled by high-precision mass flow controllers (MFCs), which have continuously adjustable flow rates and high accuracy in outputting airflow, ensuring the accuracy of test data.

Peristaltic pump injection device

The instrument is equipped with a high-precision peristaltic pump with five channels and sixteen rollers, which can simultaneously ensure the accuracy of sample injection and prevent liquid accumulation. The rotational speed of the peristaltic pump is continuously adjustable to meet various testing requirements of customers.

Ultra high resolution optical path system

The instrument is equipped with an imported grating with ultra-high resolution 4320 engraved lines, combined with optical path adjustment technology, which reduces the resolution of ordinary instruments from about 0.008nm to within 0.005nm. The ultra-high resolution ensures that there is no mutual interference between test elements.

Precision constant temperature system

The overall optical path of the instrument is protected by a precision constant temperature system, and the temperature control can be set in real time according to the actual environmental temperature of the customer's laboratory, without the need for long-term continuous adjustment. The temperature control accuracy is ≤± 0.1 ℃, and the precision constant temperature system ensures the stability of the optical path, resulting in more stable test data.

Sensitivity detector

The instrument is equipped with a high-sensitivity imported photomultiplier tube (PMT) as the detector, which can automatically set excellent test parameters for different elements to achieve excellent detection status and provide the most accurate test results. No need for refrigeration, no need for blowing, long service life.

Ultra low usage cost

When the instrument is not in operation, the power supply, cooling water tank, and gas are all turned off without any cost. The instrument can be used immediately without the need for prolonged preheating of the optical path. Using argon with a purity of 99.99% is sufficient, eliminating the need for high-purity argon at 99.999%, resulting in cost savings of at least one-third.

Automatic adjustment of observation position

The instrument adopts a two-dimensional mobile platform design, which can adjust the position of the torch tube in real time through software. The excellent observation position can be found through feedback signal values to obtain sensitivity and achieve excellent testing results.
