Overview
The Hach DR1300 FL Portable Fluorometric Colorimeter is an engineered field-deployable analytical instrument designed for trace-level quantification of free chlorine, total chlorine, and sulfite in ultrapure water systems. It operates on the principle of fluorogenic derivatization: proprietary reagents react selectively with chlorine species or sulfite to generate stable fluorescent compounds, which are then excited at 365 nm (UV LED source) and measured via a calibrated silicon photodiode detector. This fluorescence-based detection mechanism delivers exceptional specificity—effectively eliminating interferences from turbidity, color, metal ions, and organic matter that commonly compromise conventional DPD-based colorimetric methods. The instrument is purpose-built for critical process monitoring where sub-ppb accuracy directly impacts asset integrity, particularly in reverse osmosis (RO) pretreatment, boiler feedwater conditioning, pharmaceutical water-for-injection (WFI) loops, and semiconductor ultrapure water (UPW) distribution networks.
Key Features
- Trace-level detection capability: measures free chlorine and total chlorine down to 2 µg/L (ppb), and sulfite down to 6 µg/L (ppb), validated per ASTM D7805 and ISO 7393-2 methodology principles
- UV LED excitation source at 365 nm with ±1 nm wavelength accuracy ensures consistent fluorophore activation and long-term photometric stability
- IP65-rated ruggedized housing enables reliable operation in industrial environments—including humid boiler rooms, cleanroom corridors, and outdoor utility trenches
- Backlit LCD display (160 × 240 pixels) with intuitive icon-driven interface supports one-handed operation while wearing PPE
- Integrated data logging: stores up to 60 million measurement records on internal memory or optional 16 GB SD card, with automatic timestamping and user-defined sample ID tagging
- Battery-powered design: operates continuously for >100 hours on four AA alkaline cells—no external power supply required during field surveys or emergency response
- Self-diagnostic firmware with real-time error logging supports GLP-compliant audit trails and facilitates preventive maintenance scheduling
Sample Compatibility & Compliance
The DR1300 FL is compatible with standard 10 mL and 25 mL glass or high-clarity polypropylene sample vials. It accepts Hach’s ULR (Ultra-Low Range) fluorometric reagent kits—certified to NIST-traceable standards—for free/total chlorine and sulfite analysis. All reagent formulations comply with EPA Method 334.0 (chlorine) and ASTM D808 (sulfite) performance criteria. The instrument’s measurement protocol aligns with Good Manufacturing Practice (GMP) requirements for pharmaceutical water systems under USP and EU Annex 1, and supports FDA 21 CFR Part 11 compliance when paired with Hach’s compliant data export software (e.g., Hach DataCapture™ with electronic signature and audit trail functionality). Calibration verification is performed using certified fluorescent standards traceable to NIST SRM 2973.
Software & Data Management
Data export is supported via micro-USB or SD card transfer in CSV format, compatible with LIMS platforms including LabWare, STARLIMS, and Thermo Fisher SampleManager. Optional Hach DataCapture™ desktop software provides automated report generation (PDF/Excel), trend visualization with configurable control limits, and deviation alerts based on user-defined SOP thresholds. All data files include embedded metadata: operator ID, location tag, instrument serial number, calibration date, and environmental conditions (temperature/humidity logged at time of measurement). Firmware updates are delivered through Hach’s secure Customer Portal, with version-controlled release notes and validation documentation available for regulated users.
Applications
- RO membrane protection: continuous monitoring of post-carbon bed effluent to prevent oxidative damage from residual chlorine and minimize biofouling risk
- Pharmaceutical WFI systems: verification of chlorine removal prior to distillation or membrane polishing, ensuring compliance with pharmacopeial limits
- Power plant boiler feedwater: sulfite residual tracking in deaerator condensate to maintain reducing environment and suppress corrosion
- Electronics UPW loops: rapid verification of chlorine breakthrough after GAC vessels during routine system walkdowns
- F&B process water: validation of final rinse water quality in aseptic filling lines where sub-ppb chlorine may affect product stability
- Chemical manufacturing: real-time optimization of sodium bisulfite dosing in chlorine quenching applications
FAQ
What is the minimum detectable concentration for free chlorine?
The DR1300 FL achieves a method detection limit (MDL) of 2 µg/L for free chlorine under optimized field conditions, verified using Hach ULR Free Chlorine Reagent Set.
Can the instrument measure both free and total chlorine in the same sample?
Yes—sequential analysis is supported by switching between ULR Free Chlorine and ULR Total Chlorine reagent protocols within the same measurement session.
Is the DR1300 FL compliant with regulatory requirements for pharmaceutical water testing?
It meets technical suitability criteria outlined in USP , EP 2.2.43, and JP 2.05; full compliance requires integration into a validated analytical procedure per ICH Q2(R2).
How often does the instrument require recalibration?
Factory calibration is stable for 12 months; field verification with fluorescent standards is recommended before each daily use in regulated environments.
Does the device support Bluetooth or Wi-Fi connectivity?
No—data transfer is limited to USB and SD card to maintain electromagnetic compatibility in electrically noisy industrial settings and ensure cybersecurity in controlled environments.
