A standard-configuration inductively coupled plasma mass spectrometer built for quantitative trace-element work across difficult matrices. A dual off-axis ion optic and a high-speed dynamic collision/reaction cell suppress polyatomic interference, so soil digests, food homogenates and high-salt environmental samples can be run without re-tuning between matrices.
Key features
- Excellent sensitivity
- Unique reliable design, improving stability
- Easy software operation
- Excellent matrix resistance
- Preeminent interference elimination capability
- Equipped with a high-efficiency sample introduction system to maintain plasma stability and enhance sensitivity and reproducibility.
- Features advanced argon online dilution and oxygenated combustion technology for robust analysis of high-salt and organic samples.
- Adopts a stable ICP ion source with no moving parts, ensuring plasma reliability and balancing ion kinetic energy without a torch shield.
Applications
Built for environmental, food-safety and materials laboratories.
- Standard configuration ICP-MS, applicable to the quantitative analysis of various matrix samples, such as soil, food, environment and cosmetics.
- precise elemental analysis
- Inorganic elements in liquid samples
- Fully automatic heavy metal analysis system for laboratory filter membranes, soil, and etc.
- On-line monitoring system for heavy metals in surface water
- On-line monitoring system for heavy metals in atmospheric particles
- Heavy metal speciation analysis system based on LC-ICPMS
- Solid direct injection ICP-MS solves difficulties in the analysis of solid refractory samples
Choosing the right configuration
Match the sample matrix and target elements to the required detection limits, sample-introduction hardware, gas supply, exhaust, cooling, and data-system configuration. ConductScience confirms these items against the proposed method before the system is quoted.

What does this instrument measure, and who is it for?
It measures trace and ultra-trace metals in digested solids, waters and food matrices. It is built for environmental, food-safety and materials laboratories. It is a benchtop instrument intended for continuous laboratory duty, with a plumbed gas supply and extraction over the source.
What measurement principle does it use?
An argon plasma ionises the sample; a quadrupole mass filter separates the ions by mass-to-charge ratio. A collision and reaction cell ahead of the filter suppresses the polyatomic overlaps that otherwise sit on top of the analyte.
Which specifications are confirmed?
The specification table lists twenty-eight confirmed ordering parameters for this instrument. Use them to compare the operating range, utilities, and analytical performance required by the method. They include Standby RF power at 500W, Standby argon consumption at 5 L/min and Sample-introduction refrigeration temperature at <-15℃.
What should be confirmed before ordering?
Confirm argon supply and purity, exhaust extraction over the torch or spark stand, single-phase power and breaker rating, bench load rating, and cooling water where the design requires it. These are configured and quoted per installation, so raise anything unusual about the site during quote review rather than after delivery.
What else is needed to run it?
A microwave digestion system, unless your samples already arrive in solution. Elemental analysis is only as good as the dissolution that preceded it, and an incomplete digest reports a low result with no indication that anything went wrong.
How is it supplied?
This instrument is configured and quoted per installation rather than sold at a list price. Request a quote and we will confirm the configuration, the site requirements and the lead time before anything is ordered.
