S Pack DQ5 Purification Cartridge

Overview

The S Pack DQ5 Purification Cartridge is a high-integrity, single-use pre-packed column designed for the final polishing step in ultra-pure water (UPW) generation systems. Engineered for integration into Deepflow’s CYPR0LSIA1-series ultra-pure water systems, the DQ5 cartridge employs a multi-stage purification architecture combining sub-micron particulate filtration, catalytic organic scavenging, and highly selective ion-exchange resins. Its core function is to reduce total organic carbon (TOC) to <1 ppb, resistivity to ≥18.2 MΩ·cm at 25 °C, and bacterial counts to <0.01 CFU/mL—meeting ASTM D1193 Type I, ISO 3696 Class 1, and SEMI F63 specifications for microelectronics-grade water. Unlike bulk resin vessels requiring regeneration and validation, the S Pack DQ5 is factory-preconditioned, gamma-irradiated, and supplied with full lot traceability documentation—including conductivity/TOC baseline data, endotoxin testing reports (<0.001 EU/mL), and bioburden certification—ensuring immediate installation readiness and compliance with GLP and GMP water system qualification protocols.

Key Features

• Pre-packed, sterile, and pyrogen-free configuration eliminates on-site resin loading, rinsing, and sanitization steps
• Integrated 0.45 µm hydrophilic PES membrane final filter for particulate and microbial retention
• Dual-layer ion-exchange media: strong-acid cation (SAC) and strong-base anion (SBA) resins in stoichiometric balance for consistent deionization performance
• Catalytic activated carbon layer engineered for persistent removal of chloramines, ozone residuals, and low-molecular-weight organics
• Robust polypropylene housing rated for continuous operation at 0.1–0.6 MPa and temperatures up to 40 °C
• Standard 10-inch (254 mm) length × 2.5-inch (63.5 mm) diameter format compatible with ANSI/ASME B16.5 flanged or sanitary clamp interfaces
• Each unit carries a unique serial number linked to its manufacturing batch, sterilization log, and QC release certificate

Sample Compatibility & Compliance

The S Pack DQ5 is validated for use exclusively with feed water meeting Deepflow CYPR0LSIA1 system inlet specifications: conductivity ≤5 µS/cm, TOC ≤50 ppb, silica ≤0.05 mg/L, and free chlorine ≤0.05 mg/L. It is not intended for direct use with raw municipal water, seawater, or process wastewater. The cartridge complies with ISO 13485:2016 (medical device QMS), meets USP <1231> requirements for purified water distribution systems, and supports FDA 21 CFR Part 11-compliant electronic record retention when paired with Deepflow’s certified data acquisition modules. All materials of construction—including housing, gaskets (EPDM), and resin binders—are extractables-tested per USP <661.1> and ISO 10993-5 for cytotoxicity.

Software & Data Management

While the S Pack DQ5 itself is a passive hardware component, its lifecycle is fully integrated into Deepflow’s CYPR0LSIA1 system firmware. The controller logs real-time differential pressure across the cartridge, tracks cumulative flow volume (L), and calculates remaining service life based on calibrated conductivity drift and TOC breakthrough models. Upon reaching 95% capacity or exceeding 12 months from manufacture date (whichever occurs first), the system triggers an auditable alert with timestamp, operator ID, and recommended replacement action. All event logs—including installation confirmation, pressure spikes, and end-of-life notifications—are exportable as CSV or PDF for internal audit or regulatory submission.

Applications

• Final polishing stage in UPW systems serving semiconductor wafer fabrication cleanrooms (Class 10 and below)
• Feed water purification for LC-MS, ICP-MS, and atomic absorption spectroscopy instrumentation
• Preparation of reagent-grade water for cell culture media, ELISA kits, and molecular biology assays
• Support of ASTM E2915-21 accelerated stability testing protocols requiring low-ionic-background water
• Compliance-critical applications in pharmaceutical API synthesis where water quality directly impacts crystallization kinetics and polymorph control

FAQ

What is the maximum allowable operating pressure for the S Pack DQ5 cartridge?

The cartridge is rated for continuous operation at pressures between 0.1 MPa and 0.6 MPa; exceeding 0.65 MPa may compromise seal integrity and resin bed uniformity.
Can the S Pack DQ5 be reused after sanitization?

No. It is a single-use, pre-sterilized component. Reuse invalidates its QC certification, risks resin degradation, and violates ISO 21649 and USP <1231> reuse prohibitions for UPW polishing stages.
How is shelf life determined, and what happens if stored beyond 12 months?

Shelf life is defined as 12 months from manufacturing date under unopened, ambient (15–25 °C), dry storage. Extended storage may result in resin oxidation, increased leachables, and reduced TOC adsorption capacity—requiring full requalification prior to installation.
Does the cartridge include a flow direction indicator?

Yes. A permanent molded arrow on the housing clearly indicates inlet-to-outlet orientation; reverse flow causes channeling, premature breakthrough, and noncompliant effluent quality.
Is the S Pack DQ5 compatible with hydrogen peroxide vapor (HPV) sterilization cycles?

No. The cartridge is gamma-sterilized at 25 kGy during manufacturing. Exposure to HPV or other chemical sterilants may degrade the ion-exchange functional groups and compromise performance consistency.
