Overview
The P Pack S2 Pre-Purification Cartridge is a high-integrity, single-use consumable module engineered for integration into ultra-pure water (UPW) systems used in analytical laboratories, pharmaceutical QC environments, and semiconductor-grade water purification trains. Designed to operate upstream of final polishing stages—including 0.22 µm membrane filters, UV oxidation units, and ion-exchange cartridges—the S2 cartridge targets the selective removal of particulate matter, colloidal silica, organic contaminants (measured as total organic carbon, TOC), and residual divalent cations (e.g., Ca²⁺, Mg²⁺, Fe²⁺) that may compromise downstream performance or system longevity. Its functional architecture relies on a layered composite media bed comprising graded activated carbon granules, high-capacity cationic exchange resin, and sub-micron depth filtration matrix—optimized to deliver consistent pressure drop (< 0.15 bar at 2 L/min), low extractables (< 1 ppb TOC leachables per ASTM D4297), and extended service life under continuous operation at flow rates up to 3.5 L/min. The cartridge is housed in FDA-compliant polypropylene with ISO 228/1 G½ external threads and EPDM O-rings rated for repeated thermal cycling between 5–35 °C.
Key Features
- Multi-stage contaminant capture: Simultaneous adsorption (activated carbon), ion exchange (strong-acid cation resin), and mechanical retention (graded depth filter)
- Low TOC leachables profile: Validated per ASTM D4297 and ISO 3696 Grade 1 water specifications for trace organic control
- Pressure-stable design: Maintains ≤ 5% ΔP drift over nominal service life (typically 6–9 months at 2.0 L/min, depending on feed water quality)
- Non-sterile, non-pyrogenic construction: Suitable for pre-polishing in USP compliant water systems; not intended for sterile barrier applications
- Traceable lot documentation: Each unit supplied with CoA (Certificate of Analysis) including batch-specific TOC challenge test data, pressure drop verification, and endotoxin screening (< 0.03 EU/mL)
- Plug-and-play compatibility: Direct replacement for legacy P Pack S1 and S2-compatible UPW skids from major OEMs including ELGA, Veolia, and Sartorius
Sample Compatibility & Compliance
The P Pack S2 cartridge is validated for use with municipal tap water, reverse osmosis (RO) permeate, and deionized (DI) water feed streams meeting minimum conductivity thresholds of ≤ 5 µS/cm. It is not recommended for direct use with seawater, high-halide brines, or wastewater effluents without upstream pretreatment. Regulatory alignment includes compliance with ISO 3696:2012 (Water for Analytical Laboratory Use), USP Purified Water monograph requirements for organic and ionic impurity reduction, and GLP/GMP-relevant documentation standards per ICH Q5C and Annex 11. While the cartridge itself does not carry CE marking or FDA 510(k) clearance—as it functions solely as a component within a Class I or II medical device water system—it meets material biocompatibility requirements per ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization).
Software & Data Management
As a passive hardware consumable, the P Pack S2 does not incorporate embedded electronics or firmware. However, its operational lifecycle integrates seamlessly with industry-standard UPW system monitoring platforms such as Siemens Desigo CC, Emerson DeltaV, or LabVantage LIMS via analog 4–20 mA pressure differential transducers (optional add-on). End-user maintenance logs—including installation date, cumulative volume processed, and ΔP trending—can be exported in CSV format for audit-ready recordkeeping aligned with FDA 21 CFR Part 11 requirements when paired with validated electronic signature workflows. Deepflow provides optional cloud-based cartridge lifecycle tracking via its Deepflow Connect portal, enabling predictive replacement scheduling based on real-time flow-weighted usage algorithms.
Applications
- HPLC and UHPLC mobile phase preparation where organic residue interference must be minimized
- ICP-MS sample introduction systems requiring sub-ppt metal background and low carbon contribution
- Cell culture media formulation in biopharmaceutical upstream processing
- Calibration standard preparation for trace elemental analysis (e.g., EPA Method 200.8)
- Final rinse water in cleanroom component cleaning validation (ISO 14644-1 Class 5 environments)
- Feedwater conditioning for electrodeionization (EDI) modules to prevent scaling and fouling
FAQ
What is the recommended maximum operating temperature?
The P Pack S2 is rated for continuous operation between 5 °C and 35 °C. Short-term excursions up to 40 °C are permissible for ≤ 2 hours, provided inlet pressure remains below 3.5 bar.
Can this cartridge be regenerated or backwashed?
No. The P Pack S2 is a single-use, non-regenerable cartridge. Attempting chemical regeneration or hydraulic backwashing compromises structural integrity and voids the Certificate of Analysis.
How is end-of-life determined?
End-of-life is defined by either reaching 15,000 L cumulative throughput (at ≤ 2.5 L/min) or observing sustained ΔP ≥ 0.25 bar across the cartridge housing—whichever occurs first.
Is the cartridge compatible with ozone sanitization protocols?
Yes, provided ozone concentration remains ≤ 0.1 ppm residual and exposure duration is limited to ≤ 30 minutes per cycle. Extended ozone exposure degrades the activated carbon matrix and reduces TOC adsorption capacity.
Does Deepflow offer custom media configurations?
Yes. Deepflow supports OEM co-development of application-specific variants (e.g., enhanced nitrate-selective resins, low-sodium carbon blends) under NDA, with full analytical characterization and regulatory dossier support.
