Product Overview

Purpose-built measurement, clearly presented.

The U1600-L brings low-level TOC measurement into the quality-control laboratory through a compact benchtop platform with automatic sample draw, matched TIC and TC channels, UV oxidation, differential conductivity detection, touchscreen operation, electronic records, and integrated report printing.

It is designed for offline PW and WFI testing, pharmaceutical investigations and release support, cleaning-validation rinse samples, electronic ultrapure water, deionized water, and other approved low-conductivity laboratory applications. Optional database, remote, integration, standards, and qualification packages support site-specific workflows.

Distinctive Capabilities

  • Offline TOC testing from clean, non-pressurized sample bottles or containers
  • Low-level laboratory analysis using matched, temperature-compensated TIC and TC channels
  • Optional database, remote reporting, integration, standards, and qualification support
Performance & Technical Data

The measurement method and the values that matter.

How it measures

Measurement Principle

The analyzer draws sample from a non-pressurized container and divides it into matched flow paths. The unoxidized path measures total inorganic carbon (TIC), while the second path passes through a titanium-dioxide photocatalytic reactor illuminated by dual-wavelength 185 nm and 254 nm UV light to convert oxidizable organic carbon to carbon dioxide and measure total carbon (TC). Both conductivity responses are temperature compensated, and the analyzer calculates total organic carbon as TOC = TC - TIC.

Detection Limit0.001 mg/L (1 µg/L; 1 ppb)

Application Review

Application Engineering Notes

Configuration authority: The serial-number-specific nameplate, order confirmation, packing list, factory test report, calibration certificate, approved model datasheet, and written Blue Dragon clarification govern the delivered hardware and approved performance. The controlled U1600-L specification uses a 1-1600 µg/L range, 1 µg/L detection limit and resolution, approximately three-minute analysis, 0-10 µS/cm conductivity range, non-pressurized sample presentation, 16 GB storage, RS232/RS485/USB interfaces, and 370 × 350 × 220 mm dimensions.

Sample suitability: Low-level TOC work is highly sensitive to containers, tubing, handling, particles, bubbles, carryover, and environmental contamination. Sampling and wash procedures must be validated for the reporting objective.

Data integrity and compliance: User access, audit-trail, electronic-signature, storage, printing, and communication functions support regulated workflows, but compliance depends on the complete validated laboratory system and site controls.

Method Scope and Intended Use

The U1600-L is intended for offline laboratory measurement of TOC in pharmaceutical PW and WFI, electronic ultrapure water, deionized water, cleaning-validation rinse water, and other approved low-conductivity samples. It is not a general wastewater or high-salt-matrix analyzer.

Laboratory Sampling

Routine testing uses a clean, non-pressurized sample container with at least 300 mL unless the approved method specifies otherwise. Low-TOC container control, filtration where required, flushing, and bubble removal are essential to representative results.

Data Integrity and Validation Support

The standard configuration includes three-level access, audit-trail and electronic-signature functions. USP , current Ph. Eur. 2.2.44, applicable ChP workflows, and FDA 21 CFR Part 11-supporting functions require validation and procedural controls at the user site.

Configuration Control

The delivered nameplate, order confirmation, factory test report, calibration certificate, and approved serial-specific documentation take precedence over general website information.
