Description

The YG1801 Total Organic Carbon Analyzer delivers exceptional sensitivity (5ppb detection limit) through advanced UV/persulfate oxidation technology, making it ideal for ultrapure water analysis and regulated pharmaceutical applications. This precision instrument features a patented signal management system with real-time monitoring, auto-leak detection, and intelligent flow control for laboratory-quality results. The 32-bit processing system and 24-bit NDIR detector provide unmatched data resolution across its 0-10,000 mg/L measurement range.

Key technological advantages include:

• Chemical-free UV oxidation for safer operation
• PC software control with comprehensive data management
• High salinity tolerance (85g/L) for challenging samples
• Adjustable cooling module for optimal performance
• Compact benchtop design (430×455×440mm)

Priced competitively in the mid-to-high range for laboratory analyzers, the YG1801 offers outstanding value for pharmaceutical QC, microelectronics, and environmental labs requiring ultra-sensitive, reliable TOC measurements.

Frequently Asked Questions

• How does UV oxidation compare to high-temperature combustion? UV oxidation is chemical-free, requires less maintenance, and offers faster analysis (3-5 minutes) for low-TOC samples.
• Can it handle brackish water or seawater samples? Yes, with 85g/L salinity tolerance, it’s perfect for estuarine studies and coastal monitoring.
• What’s included in the PC software? The software provides full instrument control, data trending, custom reports, and 21 CFR Part 11 compliance tools.

Advantages and Disadvantages

Advantages

• Pharma-Grade Sensitivity – 5ppb detection limit meets strict USP requirements
• Eco-Friendly Operation – No hazardous chemicals required
• Regulatory Ready – 21 CFR Part 11 compliant software for validated environments

Disadvantages

• Limited Upper Range – Maximum 10,000 mg/L vs. 30,000 mg/L for combustion models
• Consumables – Requires periodic UV lamp replacement
• Gas Requirement – Needs high-purity nitrogen supply

Product Use in the Field

The YG1801 excels in:

• Pharmaceutical water systems (WFI, purified water monitoring)
• Microelectronics ultrapure water validation
• Environmental labs analyzing drinking water sources
• Beverage production quality control

Its compact footprint and quiet operation make it particularly valuable for cleanroom installations and shared laboratory spaces.

Recommendations

For optimal performance:

1. Replace UV lamp annually or per manufacturer guidelines
2. Use high-purity nitrogen (≥99.995%) for carrier gas
3. Calibrate monthly for critical applications
4. Install optional autosampler for high-throughput labs
5. Export data regularly for regulatory compliance
