Elemental Analyzer FAQ
Q: What is the maintenance schedule for an elemental analyzer?
A: Regular maintenance includes daily leak checks, weekly combustion tube inspections, monthly carrier gas system checks, and quarterly detector calibrations. The exact schedule may vary based on usage frequency and sample types.
Q: How often should I calibrate my elemental analyzer?
A: For optimal performance, we recommend performing a full calibration at least once per month or after analyzing 500 samples. Daily verification with certified reference materials is advised for critical applications.
Q: What sample preparation is required before analysis?
A: Solid samples typically need grinding to a fine powder (100-200 mesh). Liquid samples require precise measurement (1-10 μL). All samples must be homogeneous and free from contamination. Moisture content should be determined separately as it affects results.

Elemental Analyzer FAQ
Q: What is the typical lifespan of an elemental analyzer?
A: With proper maintenance, our elemental analyzers typically operate for 8-10 years in normal laboratory conditions. Critical components like detectors and combustion tubes may need replacement every 2-3 years depending on usage.
Q: Can the elemental analyzer handle corrosive samples?
A: Yes, with special configurations. We offer corrosion-resistant versions with platinum combustion tubes and specialized detection systems for analyzing halogen or sulfur-rich samples that could damage standard components.
Q: How much gas consumption can I expect?
A> Gas consumption averages 5-10 L/min during operation. Our models feature optimized gas flow systems that reduce consumption by 30% compared to conventional analyzers, saving on operational costs.
Performance Data
| Element | Precision (RSD) | Accuracy | Typical Sample Size |
|---|---|---|---|
| Carbon (C) | ≤ 0.5% | ± 0.3% absolute | 2-5 mg |
| Hydrogen (H) | ≤ 1.0% | ± 0.2% absolute | 2-5 mg |
| Nitrogen (N) | ≤ 0.5% | ± 0.3% absolute | 2-5 mg |
| Sulfur (S) | ≤ 1.0% | ± 0.2% absolute | 5-10 mg |
| Oxygen (O) | ≤ 1.5% | ± 0.5% absolute | 2-5 mg |
Elemental Analyzer FAQ
Q: What training is provided with the elemental analyzer?
A: We offer comprehensive on-site training including 2 days of hands-on instruction covering operation, maintenance, troubleshooting, and data interpretation. Additional training modules are available for advanced applications and method development.
Q: How does the elemental analyzer handle very low concentration samples?
A: For trace element analysis, we recommend using our high-sensitivity detector option which extends the lower detection limit by 10-100 times. Special sample preparation techniques and increased analysis time may be required for ultra-trace work.
Q: What safety features are included?
A> Our elemental analyzers feature multiple safety systems including over-temperature protection, gas leak detection, pressure monitoring, and emergency shutdown. The combustion chamber is fully insulated and all hot surfaces are protected.
