Vigor SPS Solvent Purification System

Overview

The Vigor SPS Solvent Purification System is an engineered solution for continuous, on-demand purification of organic solvents under inert atmosphere conditions. Based on integrated high-efficiency solid-phase purification columns—typically employing activated alumina, copper catalysts, and molecular sieves—the system removes trace water, oxygen, peroxides, and other reactive impurities via controlled flow-through adsorption and catalytic reduction. Each purification module operates under positive nitrogen or argon pressure to prevent atmospheric ingress, enabling consistent delivery of solvents meeting stringent specifications for air- and moisture-sensitive applications including organometallic synthesis, battery electrolyte formulation, and thin-film deposition. The SPS platform supports modular deployment (3-, 5-, or 7-solvent configurations), allowing laboratories to scale purification capacity without compromising footprint or operational integrity.

Key Features

• Modular architecture supporting 3-, 5-, or 7-solvent independent purification channels—each with dedicated column regeneration logic and real-time status monitoring.
• Per-channel purification capacity of 800 L per column set (based on standard solvent types such as THF, toluene, hexanes, DCM, and acetonitrile), with column lifetime tracked via integrated flow-time logging and pressure differential sensing.
• Integrated inert-gas management system with automatic purge cycles, pressure-regulated dispensing, and dual-stage gas filtration (particulate + hydrocarbon trap) to maintain <1 ppm O₂/H₂O in the delivery headspace.
• Explosion-proof electrical design compliant with IEC 60079-0 and GB/T 3836.1 standards; fully compatible with Class I, Division 2 flammable liquid storage cabinets.
• Optional direct integration interface with Vigor inert-atmosphere gloveboxes (e.g., VGB series), enabling seamless solvent transfer without exposure to ambient air—critical for Schlenk-line-free workflows.
• Touchscreen HMI with multilingual UI (English default), configurable alarm thresholds, and local data logging of column usage, purge duration, and dispense volume per solvent channel.

Sample Compatibility & Compliance

The SPS system accommodates a broad range of common aprotic and protic organic solvents—including tetrahydrofuran (THF), diethyl ether, toluene, benzene, dichloromethane (DCM), chloroform, acetonitrile, methanol, ethanol, and dimethyl sulfoxide (DMSO)—subject to compatibility verification with column chemistries. All wetted materials are electropolished 316L stainless steel or PTFE-lined to ensure chemical resistance and minimize leachables. The system meets structural and labeling requirements per GB 50016 (Chinese Fire Code) and aligns with laboratory safety practices referenced in ASTM E2525 (Standard Guide for Safe Handling of Air-Sensitive Reagents). While not certified to UL/CSA for North American installation, its mechanical and electrical architecture supports third-party validation for GLP-compliant environments where audit trails and operator access control are implemented at the facility level.

Software & Data Management

The embedded control firmware records time-stamped operational events—including column activation, regeneration initiation, total dispensed volume per solvent, and pressure anomalies—with local storage (SD card, 8 GB) retaining ≥12 months of compressed event logs. Export is supported via USB 2.0 in CSV format for integration into LIMS or electronic lab notebooks (ELN). Audit trail functionality includes user login tracking (with role-based permissions), critical parameter change history, and tamper-evident log signing. Though not natively 21 CFR Part 11 compliant, the system’s deterministic behavior, non-volatile memory retention, and exportable immutable logs enable qualification under FDA-regulated QC labs when deployed with documented SOPs and periodic integrity verification.

Applications

• Synthesis of highly reactive species (e.g., Grignard reagents, alkyllithiums, low-valent transition metal complexes) requiring <1 ppm H₂O/O₂ solvents.
• Preparation of lithium-ion and solid-state battery electrolytes where residual water induces HF formation and cathode degradation.
• Chemical vapor deposition (CVD) and atomic layer deposition (ALD) precursor solutions demanding sub-ppm impurity profiles.
• High-performance liquid chromatography (HPLC) mobile phase preparation for trace-metal analysis and polymer characterization.
• Quality control testing in pharmaceutical development labs performing USP <467> residual solvent analysis using GC–MS.

FAQ

What solvents are validated for use with the SPS system?

Vigor provides validated protocols for THF, toluene, hexanes, DCM, acetonitrile, and ethanol. Other solvents require compatibility assessment based on polarity, boiling point, and reactivity with column media.
Can the SPS be installed outside a fume hood?

Yes—when configured with explosion-proof components and housed in a certified flammable-liquid cabinet meeting NFPA 30 or GB 50160 requirements, external hood placement is permissible.
How is column exhaustion determined?

Exhaustion is inferred from sustained increase in outlet dew point (>5 °C rise over baseline), elevated backpressure (>15% above initial), or cumulative dispense volume approaching 800 L per column set—whichever occurs first.
Is remote monitoring supported?

The base system does not include Ethernet/Wi-Fi connectivity; however, analog 4–20 mA outputs and Modbus RTU (RS-485) are available as factory options for integration into building management or SCADA systems.
Does Vigor offer column regeneration services?

Yes—Vigor provides off-site column reactivation and analytical verification (Karl Fischer titration, GC-TCD residual O₂) under ISO/IEC 17025-accredited procedures, with full certification documentation.
