In response to the growing testing needs in the fields of food, drug, environment, and third-party testing, Puyu Technology has developed the 7000 series of inductively coupled plasma mass spectrometers with the support of the “National Major Scientific Instrument and Equipment Development Project”. It has overcome the core technical difficulties of mass spectrometry, such as high-temperature gas flow field control, multi-stage gradient vacuum, high-sensitivity ion interface, distributed collision reaction cell, and quadrupole mass analyzer resistant to temperature and humidity changes. It has excellent sensitivity, lower detection limit, excellent stability and wider dynamic linear range, meeting the needs of trace element analysis in various samples.

DESCRIPTION

Performance advantages

Excellent sensitivity

Based on the aerodynamic simulation design at the junction of thermal plasma and vacuum, the ion interface is optimized, and the sensitivity of ICP-MS is improved by 3~5 times, which can easily cope with the quantitative analysis of various common samples such as environment, food, pharmaceuticals, materials, etc.

Excellent matrix resistance

Through key technologies such as fluid simulation ion interface, two off-axis design, innovative collision reaction pool, powerful self-excited all-solid-state ICP ion source and argon online dilution, the 7000 has better matrix resistance and can easily cope with the analysis of various complex matrix samples.

Innovative reliability design to improve stability

The 7000 can be operated on board. The product has undergone special shock absorption and all-solid-state design. Through comprehensive road spectrum testing for on-board road conditions and actual combat exercises of tens of thousands of kilometers, it has excellent reliability.

Customized ICP-MS solves special application problems

The fully automatic heavy metal analysis system (7020 model) combined with graphite digestion/microwave digestion provides standardized sample pretreatment methods and instrument analysis methods. It can customize and develop various special applications for samples from different industries. It has stable performance, reliable data, and eliminates human measurement uncertainty to the greatest extent.

Rich accessory systems solve special application problems

It can be equipped with a rich accessory system such as fully automatic graphite/microwave, fully automatic ion exchange, high performance liquid chromatography, solid direct injection, atmospheric particulate online injection, fast injection, organic injection, automatic sampler, etc. to meet the analysis needs of various application scenarios.

Application areas

Environmental protection: including analysis of tap water, surface water, groundwater, seawater, and various soils, sludge, waste, etc.

Food safety: hygiene and epidemic prevention, commodity inspection, quality control of foods such as tobacco and alcohol, identification of authenticity, etc.

Clinical medicine: analysis of hair, blood samples, urine samples, biological tissues, and biological mechanism research of proteins, enzymes, etc., drug quality control, etc.

Alloy materials: analysis of steel alloys, glass, ceramics, mining and metallurgy, etc.
