- Sample Type & Phase
- Low-conductivity high-purity water, including pharmaceutical PW, WFI, electronic ultrapure water, deionized water, and other approved water matrices. Wastewater, concentrated process streams, high-salt matrices, and suspensions require written application review and are normally outside the approved method.
- Measurement Range
- Confirm expected TOC level, alert and action limits, required reporting units, calibration range, system-suitability requirement, and applicable site or pharmacopoeial procedure. The approved working range is 1-1600 micrograms/L carbon with a 1 microgram/L detection limit.
- Sample Conditions
- Provide sample pressure, temperature, conductivity, cleanliness, particle content, sanitization temperature, organic load, flow availability, and sampling-point arrangement. Standard sample temperature is 1-50 degrees C; hotter service requires the approved condenser.
- Sample Handling
- Define sanitary take-off, safe isolation, pressure and flow control, 3 mm sample tubing, flushing, low-TOC-compatible materials, optional 60 micrometre or smaller particle filtration, cooling where required, unrestricted drain, and representative sample transport.
- Installation Area
- Confirm wall-mount location, clean and dry non-hazardous environment, 10-40 degrees C ambient, service and ventilation access, proximity to the loop, drain location, network access, and any washdown, corrosive-vapor, or outdoor limitations.
- Utilities
- Provide grounded 220 VAC matching the delivered nameplate, at least 0.3 MPa upstream of the controlled sample arrangement, 6-10 mL/min analyzer flow, unrestricted near-atmospheric drain, communication cabling, approved standards, and condenser utilities when ordered.
- Response Requirement
- Define continuous monitoring, scheduled verification, quality investigation, release support, alarm response, or trend monitoring. The published analysis time is approximately three minutes per test, excluding sample transport and flushing.
- Integration Requirement
- Confirm RS232, RS485, USB, and Ethernet use, network settings, alarms, report and printer configuration, remote or database options, historian or LIMS workflow, user roles, audit trail, electronic signatures, data retention, backup, and cybersecurity responsibilities.
- Commissioning Requirement
- Verify mounting, grounded power, safe isolation, sample pressure and 6-10 mL/min flow, unrestricted drain, leak integrity, low-TOC water, calibration standards, verification and system suitability as applicable, interfaces, alarms, reports, user accounts, audit trail, backup, training, and handover documents.
