The ICP‑ICP‑OES, or inductively coupled plasma optical emission spectrometer, utilizes a high‑temperature plasma to ionize samples, enabling precise determination of a wide range of inorganic elemental constituents. It can simultaneously analyze metals, heavy metals, and certain nonmetals, offering low detection limits and a broad linear dynamic range. Suitable for analyzing water, ores, food, chemical raw materials, and other sample types, it features straightforward sample preparation and rapid analysis, making it widely employed in quality control, environmental monitoring, and materials research and development. It provides quantitative elemental analysis with stable and reliable data.

The ONH-3000 Oxygen–Nitrogen–Hydrogen Analyzer employs pulse heating and infrared thermal conductivity detection, enabling rapid and accurate determination of oxygen, nitrogen, and hydrogen in solid inorganic materials across the full concentration range—such as steels, metal powders, nonferrous metals, ceramics, and minerals. Utilizing thermal extraction analysis, it measures residual hydrogen by heating the sample at temperatures below its melting point, while simultaneously analyzing oxygen, nitrogen, and hydrogen in solid inorganic samples using a single instrument. This instrument offers technical advantages including a wide analytical range, low detection limits, a simplified measurement procedure, and the use of a single carrier gas.

The instrument can be equipped with up to five dispersion systems, offering broad adaptability. The water‑circulation dispersion system is suitable for conventional samples; the dry‑dispersion system accommodates easily soluble samples and magnetic materials; the micro‑dry‑dispersion system is ideal for valuable samples such as active pharmaceutical ingredients; and the solvent‑based circulation dispersion system, along with the micro‑sample cell system, is designed for water‑soluble samples. Additionally, it features advanced automated functions—including automatic testing, automatic water intake, automatic drainage, automatic bubble removal, and automatic cleaning—streamlining operation, minimizing human‑induced variability in test results, and further enhancing repeatability and accuracy.

The Hall flowmeter is manufactured in accordance with the GB 1482‑2010 standard for the determination of flowability of metal powders. It is used to measure the flow rate and tapped density of both metallic and non‑metallic powders. This instrument is suitable only for powders that can freely pass through a standard funnel with an aperture of 2.5 mm or 5.0 mm. Other sections of this standard specify methods for determining the tapped density of powders that cannot pass through a standard funnel with a 5.0‑mm aperture. The powder is allowed to fall freely from the funnel opening onto a measuring cup from a specified height. In the tapped state, the tapped density of the powder is expressed as the mass of the powder per unit volume.

The powder testing parameters include angle of repose, collapse angle, plane angle, difference angle, dispersibility, loose bulk density, tapped density, compressibility, porosity, agglomeration index, uniformity index, flowability index, and pourability index. The equipment measures angles using the goniometer method, with a measurable range of 0–90 degrees; the tapping frequency for tapped density is 250 cycles per minute, and the tapping amplitude can be set to either 3 mm or 14 mm.

It can be used for particle size and shape analysis of metal powders such as aluminum powder, zinc powder, molybdenum powder, tungsten powder, magnesium powder, copper powder, as well as rare‑earth metal powders and alloy powders. By employing a high‑performance lens and a unique oblique laser incidence configuration, it achieves full‑angle collection of scattered light signals under single‑beam conditions. This not only replicates the effect of multi‑beam techniques—commonly used in imported instruments—to broaden the scattering angle but also eliminates the connection errors caused by fragmented scattered‑light signals and the refractive index deviations arising from multiple wavelengths, thereby enhancing measurement accuracy. Moreover, it enables precise particle‑size analysis of samples ranging from nanoscale to micrometer‑scale and even millimeter‑scale.

The powder chromatograph dissolves powdered samples and, through chromatographic separation, precisely detects components such as additives, residual solvents, and impurities. It is available in gas‑phase and liquid‑phase models. The instrument offers high resolution and low detection limits, and when paired with an automated sample‑injection module, it delivers stable, high‑throughput analysis. Widely used for quality control of pharmaceuticals, chemicals, and food powders, it enables rapid qualitative and quantitative analysis, with software that automatically generates chromatograms to meet the needs of both R&D and production‑line quality control.
