Maximum Uptime and Reliability: Any Application, Any Condition
Hach BioTector B7000 TOC Analyzers use a patented self-cleaning oxidation technology (TSAO) to easily handle difficult samples and significantly reduce the maintenance schedule and costs associated with traditional on-line measurement.
Key benefits include:
- Superior reliability—Typically 99.7% uptime.
- High dependability—Patented two-stage advanced >oxidation technology handles even the most challenging applications involving fats, oils, greases, salts, sludge, and particulates.
- Intelligent design—Self-cleaning technology and oversized tubing eliminates filtration and prevents clogging and sample contamination.
- Minimal maintenance—No calibration or service required between 6 month service interval.
- Low cost of ownership—Provides a quick pay back with cost savings in chemical dosing, waste reduction and optimized processes.
Technology Comparison
| TSAO (BioTector) | Thermal | UV Persulfate | |
|---|---|---|---|
| Calcium and salt | Causes no impact with chlorides up to 30% and calcium up to 12%. | Leads to analyzer failure due to collection of un-oxidized particulates in the furnace. | Reduces persulphate oxidation potential with concentration as low as 0.05% |
| Algae growth | Does not impact the analyzer due to automatic self-cleaning feature. | Collects in the sample system, leading to plugging. | |
| Microfilters and pre-filter systems | Eliminates the need for filtering due to 3.2mm sample tubes which handle up to 2 mm particulates. | Requires filtering to prevent plugging of very small sample tubes (0.5 mm) and microsyringes. | Requires filtering to prevent plugging of very small sample tubes and micro-slider valves. |
| Oils, fats and greases | Self cleans in approximately 12-24 minutes. | Must shut down analyzer to clean and maintain regularly. | Loses measurement for approximately 12-24 hours. |
| Measurement drifts | Allows a 6-month calibration interval due to TSAO method and high quality build. | Requires calibration every 2-3 days due to furnace buildup and IR bench contamination. | Requires calibration every 2-3 days due to UV light source scaling that causes incomplete oxidation and drift. |
| Automatic self-cleaning capability | Includes automatic self-cleaning of the reactor and sample system with every reaction. | Not available. Requires analyzer to be offline for 1 hour for manual cleaning. | |
