The DT-GWJ-4 intelligent particle detector is a high-performance instrument designed for the detection of insoluble particles in injectable solutions. Utilizing laser technology and a touch-screen interface, this device offers seven-channel analysis to meet the requirements of the Chinese Pharmacopoeia 2005 edition. It is ideal for testing contaminated injections, filtered infusions, anesthesia equipment, and drug packaging, as well as for particle size analysis in liquid and solid powder samples across various industries such as petrochemicals and metallurgy.
**Applications:**
1. Detection of insoluble particles in injections (including intravenous and small-volume injections), meeting USP standards for particle detection in the U.S., China, and other countries.
2. Testing for contamination in infusions and filters.
3. Particle size analysis of solid powders in liquid environments within the chemical, petroleum, and metallurgical industries.
**Features:**
- Supports a wide range of transparent dispersion media, including colorless, colored, and emulsified samples, allowing direct detection without pre-treatment.
- High-speed operation, with a single test taking only 20 seconds.
- Enhanced stability through a unique dual-loop light circuit, ensuring consistent performance and reliable measurement results.
- Excellent reproducibility, with a coefficient of variation (CV) below 2% for particle concentrations above 1,000 per mL.
- User-friendly interface with a large LCD touchscreen and full Chinese graphical display.
- Capable of directly detecting various injection packaging types, such as bottles, pouches, and vials.
- Seven-channel detection with a minimum detectable particle size of 2μm and a wide measurement range of 1–250μm.
- Supports 1ml and 5ml sample volumes for precise quantitative analysis of small injections and infusions.
- Real-time display of all seven channels' results, with options for particle distribution analysis and self-diagnostic functions.
- Complies with multiple international standards and can be used for testing infusion content, anesthesia equipment, and drug packaging materials.
- Equipped with an electromagnetic stirrer that ensures even suspension of particles, minimizes bubble formation, and allows adjustable stirring speed.
- Automatic sampling head descent for easy handling and a closed detection chamber to prevent airborne contamination.
- Built-in automatic recoil function for efficient sample handling without the need for external syringes.
- Open drainage system for waste disposal into open containers or directly into sewers, eliminating the need for frequent cleaning.
- Standard serial port for connection to a computer, enabling data storage and retrieval via specialized software for long-term record-keeping and regulatory compliance.
