Taiwan Hallmark's product line of Total Organic Carbon (TOC) analyzers is a networkable family of modular components that can be custom-combined for on-line measurement of all TOC concentrations found within high-purity water distribution systems, from the most demanding ultra-pure rinse applications to the higher organic content of drinking, reclaim, and wastewaters.

Our family of analyzers provides measuring capability from part-per-trillion (ppt) through part-per-million (ppm) concentration of organic compounds. The model A-1000XP TOC Analysis System measures TOC concentrations between 0.020 (20 ppt) to 1.999 parts-per-billion (ppb). The model A-1000 measures concentrations between 0.05 (50 ppt) and 1999 parts-per-billion (ppb). The ACCESS 643 measures TOC concentrations between 1 and 1000 parts-per-billion (ppb), and the model A-2000 between 20 ppb and 1000 parts-per-million (ppm).

The models A-1000, A-1000XP, and ACCESS 643 are similar in that they all use the same reagentless photocatalytic oxidation technique that determines TOC from the highly stable measurements of conductivity and temperature. The A-1000XP provides the highest sensitivity and highest resolution, and is used primarily in the most demanding ultra-pure semiconductor applications. The A-1000 is used throughout the semiconductor, pharmaceutical, and power industries. ACCESS 643 incorporates a uniquely versatile sampling system designed specifically to meet the USP 23 <643>TOC and <645>Conductivity methods of the pharmaceutical industry. These instruments all utilize the same controller, printer, and connector block, with similar enclosures for permanent and portable installations.

The model A-2000 extends the TOC measurement range to the higher concentrations found in drinking, feed, reclaim, waste, and cleaning effluent for all water use industries. To accommodate these higher TOC concentrations, the A-2000 utilizes an industry standard wet chemistry and NDIR technology. The supplied reagents, as well as controller, printer, and connectors are contained within a splash-proof enclosure. It supports multiple sampling systems that facilitate laboratory, manual and on-line applications.

All Taiwan Hallmark instruments and components are designed with built-in network capability on Taiwan Hallmark's proprietary ANET system. The Gateway Interface allows connection of the network to a computer or printer. Results from all of the sensors can be printed in three different report formats or sent to a computer for user-customized data processing.

Many of our customers are concerned about the possible effect that the Year 2000 may have on Taiwan Hallmark's instrumentation, reports, and systems associated with our products. We have studied the problem and tested our instruments. We have determined that all Taiwan Hallmark instruments are in compliance with the requirement for the rollover to the new millenium. The first time stamp on any report in the Year 2000 will reflect accurately the time, date, and year. When the Year 2000 arrives, the instruments will continue to collect and report data correctly.

All Software used at Taiwan Hallmark to produce documents, reports, and analysis for ongoing company business is being evaluated for Year 2000 compliance. We are evaluating this complex issue with our vendors to ensure that they are also Year 2000 compliant. We are continuously testing all business computer software for compliance and implementing new software as necessary.

Taiwan Hallmark's A-1000 has an excellent reputation and a proven record for TOC monitoring, and has become the monitoring standard in the semiconductor industry. Its patented analysis method has led the industry with a low 0.05 ppb TOC detection limit while completely oxidizing a sample in as little as 2 minutes. The instrument's automatic on-line convenience means no complicated grab sample protocols and associated sources for contamination, which provides a lower cost of ownership. Available in both stationary (S-10) and portable (S-20P) configurations, it is perfect for both permanent-point or spot check, troubleshooting operation.

The unique technology involves the photocatalytic oxidation of water captured in the analysis cell. Instead of wet chemistry, the reagentless design uses pure titanium, in the presence of high-energy ultraviolet (UV) light, to fully oxidize each sample. Successive samples are processed automatically and the results can be printed in 3 types of pre-formatted reports. The user-friendly menu-driven interface displays TOC, resistivity/conductivity, temperature, trend and sample profile, while continual operation by one intermittent valve provides low maintenance along with very high reliability.

The C80 Controller sets parameters and displays sensor data for as many as eight different ACCESS 643 or A-1000 instruments located throughout your water distribution and make-up systems. (Desktop case shown is optional).

The model A-1000 S20P Portable TOC Analyzer combines the S10 sensor with the C80 Controller, printer, and carrying handle to make a completely portable unit. It can be conveniently carried to different sites within a water system for short-term monitoring applications and to provide hard copy reports of the results at user-selected intervals.

The A-1000XP version of the A-1000 analyzer uses the same proven technology of the analysis cell with its patented catalyzed photo-oxidation process. In addition, the inlet ports have been optimized to eliminate any chance of contamination during the sample introduction. The ultra-clean inlet system combined with advanced electronics and enhanced software algorithms have improved instrument signal detection and allow us to report TOC levels accurately and reliably to 0.02 (20 ppt), with an unprecedented display resolution of 0.001 ppb, even when dissolved oxygen levels are less than 5 ppb. This outstanding performance provides maximum sensitivity for detecting the smallest TOC changes that could be expected in an ultrapure water system.

The A-1000XP is a stand-alone, portable unit that includes the C80 Controller to maintain the familiar user-interface, and a printer for immediate hard copy reports. ANET networking capability with all of Taiwan Hallmark's TOC analyzers is built-in with the standard Taiwan Hallmark I/O connector block.

ACCESS 643 stands for Automated Calibration, Conductivity, & Expert System Suitability and is designed specifically for the pharmaceutical industry to meet the USP Method <643>for TOC and Method <645>for Conductivity. It's uniquely designed sample introduction module simplifies the test protocol required by these methods, while recording the complete documentation necessary.

The portable model combines the ACCESS 643 sensor with the C80 Controller, printer, and handle. It can be conveniently carried to different sites within the water system for short-term monitoring applications and to provide hard copy reports of the results at user-selected intervals.

The wall mount or stationary version can be strategically located on-line throughout the water system and linked to Taiwan Hallmark's local area network for instrument control and data acquisition and display.

Taiwan Hallmark's A-2000 Wide-Range TOC Analyzer is ideal for monitoring feedwater, reclaimed water, and processed drinking water at TOC concentrations that are typically in the part-per-million range. Its optional laboratory autosampler fulfills the Information Collection Rule (ICR) for TOC measurement from multiple sites, while the same instrument's automatic on-line operation meets the requirements for continuous TOC measurement under the Disinfectant Byproducts Rule (DBR).

It also features automatic validation, preprogrammed calibration, and stores up to 5 replicates for each of 5 standard concentrations, with pre-formatted Validation and Calibration reports. Calibration can be performed with any standard calibration material, including sucrose, or KHP.

The A-2000 saves time with automatic calibration and validation, and pre-formatted report generation from the standard built-in or optional external printer.

The A-2000 uses the standard method required by the EPA for measurement of TOC in wastewater. Its wide range, fast analysis, and ability to accommodate most industrial effluent streams, make it an ideal wastewater analyzer.
