FAQs

1. What are the key factors to consider when selecting this analytical equipment for laboratory use?

When selecting this analytical equipment, key factors include: 1) The instrument's precision and accuracy to meet experimental requirements; 2) Compatibility with the types of samples and applications you will be working with; 3) Ease of use and maintenance requirements; 4) Safety features to protect operators and samples; 5) Calibration and certification requirements; 6) Cost-effectiveness and long-term reliability; 7) Technical support and service availability from the supplier. Evaluating these factors ensures that the instrument meets your laboratory's specific needs.

2. How often should this analytical equipment be calibrated to ensure accurate results?

It is recommended to calibrate this analytical equipment at least once every 6-12 months under normal usage conditions. More frequent calibration (every 3-6 months) may be necessary if: 1) The instrument is used continuously for extended periods; 2) It is exposed to harsh environmental conditions (temperature fluctuations, humidity, dust); 3) It is used for critical applications requiring high precision; 4) The instrument has been moved or subjected to physical shock; 5) Calibration checks indicate significant deviations from standard values. Always follow the manufacturer's calibration guidelines.

3. What are the common maintenance procedures required for this analytical equipment?

Common maintenance procedures include: 1) Regular cleaning of the instrument's exterior and sample contact surfaces to prevent contamination and ensure proper operation; 2) Inspection of moving parts (if applicable) for wear and lubrication as recommended by the manufacturer; 3) Replacement of consumable parts (filters, bulbs, reagents) according to usage guidelines; 4) Verification of performance parameters (temperature, pressure, voltage) regularly; 5) Storage of the instrument in a clean, dry environment when not in use; 6) Keeping a maintenance log to track service activities and identify potential issues early; 7) Following the manufacturer's specific maintenance schedule for optimal performance and longevity.

4. Can this analytical equipment be used with different types of samples, and are there any compatibility considerations?

Yes, this analytical equipment can be used with a variety of sample types, but compatibility considerations are important: 1) Check if the instrument's materials are compatible with the chemical composition of your samples (avoid corrosive or reactive substances that may damage the instrument); 2) Ensure that the sample volume and concentration are within the instrument's recommended range; 3) For biological samples, consider sterility requirements and potential cross-contamination risks; 4) For volatile or hazardous samples, ensure proper ventilation and safety precautions are in place; 5) Consult the manufacturer's documentation for specific sample compatibility guidelines, and perform compatibility tests with new sample types before regular use.

5. What should be done if the analytical equipment malfunctions or produces inconsistent results?

If malfunctions or inconsistent results occur: 1) First, check the instrument's user manual for troubleshooting guidelines specific to the issue; 2) Verify that the instrument is properly calibrated and within its calibration period; 3) Inspect for obvious issues such as loose connections, damaged parts, or incorrect settings; 4) Clean the instrument thoroughly to remove any contamination that may affect results; 5) Repeat the experiment with a known standard sample to determine if the issue is with the instrument or the sample; 6) If the problem persists, discontinue use of the instrument to prevent further damage or inaccurate results; 7) Contact technical support or a qualified service technician for diagnosis and repair, providing details of the issue and any troubleshooting steps already performed.

1. What is the working principle of the Laser Particle Size Analyzer ?

Laser Particle Size Analyzer works on the principle of laser diffraction using converging Fourier transform optical path technology. As laser light passes through a dispersed sample, particles scatter light at angles inversely proportional to their size. The analyzer detects this scattered light through a 96-channel detector system to calculate an accurate particle size distribution.

2. What are the advantages of its wet dispersion method in sample testing?

The wet dispersion method in Laser Particle Size Analyzer prevents particle agglomeration and ensures consistent suspension through ultrasonic dispersion (40 kHz, 100 W). This is particularly beneficial for cohesive or fine powders that might clump in dry conditions, offering better analysis of suspensions, emulsions, and powders.

3. What type of computer system is required to operate the ?

The Laser Particle Size Analyzer operates via computer-based control. While minimum system requirements may vary, it typically requires a Windows-based system with compatible software provided by It for real-time control, data visualization, and reporting.

4. How does the handle fluid circulation and mixing during sample analysis?

Laser Particle Size Analyzer features a circulation flow rate adjustable from 0 to 30 L/min with a 25 W pump, and a high-speed circulation mixing mechanism that operates between 100 to 33950 rpm. This ensures effective sample homogenization and dispersion for accurate analysis.
