Inductively Coupled Plasma Spectrometers (ICP)

Instrument introduction

PZ-ICP-2000 Inductively Coupled Plasma Spectrometers can detect approximately 70
trace to constant elements in different materials. They are widely used in scientific research Institutes, colleges, and other industry enterprises related to the fields such as geology, metallurgy, rare earth materials, electro-plating, cement, petroleum, chemical engineering, environmental detection, non-ferrous metals, medical science, food and agriculture.

Performancecharacteristics

Simultaneous measurement of multi elements
Low detection limit: 0.1-10ppb, and even lower
Wide density linear range, 5-6 orders of magnitude
Less chemical interference, maximum accuracy, RSD≤2%
High analysis speed,low cost

High Frequency Box
High Frequency Box excites very stable plasma torch by exploiting the inductively feedback self-oscillation circuit. The circuit is transmitted by coaxial cable,
matchingly tuned and implements close-loop auto-control by means of power feedback (National Patented Invention). Industrial argon can be used in this kind of generator, which not only makes the lighting the ICP torch easy but
also saves the cost of highly purified argon.
Match box
The high performance match box is composed of vacuum ceramic adjustable capacitors and gas adjustable capacitors, which allows it to reach the best match state and achieve maximum effective output on load coils.
Directional coupler
The stability of power output is achieved by controlling the anode voltage of oscillation valve after the power signals are sent out of the directional coupler and get amplified by the amplifier.
