Sanotac S0150 High-Pressure Liquid Chromatography (HPLC) Pump

Overview

The Sanotac S0150 High-Pressure Liquid Chromatography (HPLC) Pump is an isocratic solvent delivery system engineered for precision, long-term stability, and seamless integration into analytical and preparative chromatographic workflows. It operates on a dual-piston series configuration with a floating piston design—a mechanical architecture optimized to minimize mechanical hysteresis, reduce seal wear, and ensure consistent volumetric displacement across the full flow range. The pump delivers mobile phases at pressures up to 50 MPa (7250 psi), supporting ultra-high-performance liquid chromatography (UHPLC)-compatible column hardware and sub-2 µm particle packings. Its core function—accurate, pulse-minimized, and programmable solvent delivery—is foundational to retention time reproducibility, peak shape integrity, and quantitative reliability in regulated environments including pharmaceutical QC, clinical diagnostics, and environmental analysis.

Key Features

• High-fidelity flow control: Achieves ±0.1% flow accuracy and ≤0.1% RSD over 0.001–9.999 mL/min, enabled by multi-point volumetric calibration and real-time cam-profile compensation.
• Low-pressure pulsation design: Integrated electronic pulse suppression and optimized cam geometry limit pressure fluctuation to ≤0.1 MPa, critical for baseline stability in UV, fluorescence, and mass spectrometric detection.
• Durable wetted path: Constructed with 316L stainless steel housings, sapphire check valves, ceramic pistons, and PTFE seals—resistant to aqueous, organic, and mildly corrosive mobile phases.
• Column protection logic: Programmable pressure limit setting, zero-point offset correction, and automatic pressure hold/abort functions safeguard analytical columns and system integrity.
• Piston maintenance optimization: Built-in post-piston wash cycle reduces residue accumulation and extends seal service life—particularly beneficial in high-salt or viscous solvent applications.
• Flexible I/O architecture: Standard RS232 and USB interfaces; optional RS485/RS422 support; compatible with Modbus RTU/ASCII and proprietary Sanotac protocol for bidirectional command-response control.

Sample Compatibility & Compliance

The S0150 supports a broad spectrum of chromatographic modalities—including reversed-phase, ion-exchange, size-exclusion (SEC/GPC), hydrophilic interaction (HILIC), and post-column derivatization systems. Its flow and pressure specifications align with ASTM D7091 (for polymer analysis), ISO 13877 (liquid chromatography performance verification), and USP (chromatography system suitability). When deployed in GxP-regulated environments, the pump’s deterministic control loop, audit-trail-capable firmware (via optional remote software), and configurable method parameters support compliance with FDA 21 CFR Part 11 requirements for electronic records and signatures. Its modular design facilitates integration into GLP/GMP-compliant HPLC, IC, and IVD platforms—such as hemoglobin A1c analyzers, amino acid analyzers, and online reaction monitoring systems.

Software & Data Management

The S0150 operates with embedded firmware supporting both local and remote operation modes. Local control includes real-time graphical display of flow rate vs. pressure trends, program progress visualization, and on-device method storage (up to 20 user-defined protocols). Data logging captures timestamped flow and pressure values at user-selectable intervals (100 ms–10 s), exportable in CSV format with optional XY plot generation. Remote operation—enabled via optional PC-based software—provides full parameter adjustment, method sequencing, alarm history review, and firmware update capability. All communication layers adhere to deterministic timing constraints, ensuring synchronization with external detectors and fraction collectors. Integration with SCADA, DCS, or PLC systems is supported through standard industrial protocols (Modbus RTU/ASCII), enabling centralized batch tracking and process validation documentation.

Applications

• Pharmaceutical quality control: Isocratic elution for assay validation, dissolution testing, and reference standard quantification under ICH Q2(R2) guidelines.
• Clinical diagnostics: Reliable solvent delivery in automated HbA1c analyzers and amino acid profiling instruments requiring long-run stability and low carryover.
• Environmental testing: Robust operation with buffered eluents in ion chromatography for anion/cation analysis per EPA Methods 300.0 and 300.1.
• Materials science: Precise reagent infusion in gel permeation chromatography (GPC) and polymer molecular weight distribution analysis.
• Process analytical technology (PAT): Coupled with inline UV/VIS or conductivity detectors for real-time reaction monitoring in continuous flow synthesis.
• OEM instrumentation: Modular form factor and open communication architecture make it suitable for embedding into third-party analytical devices, including microfluidic platforms and point-of-care diagnostic systems.

FAQ

What is the maximum operating pressure and corresponding pressure unit conversion?
The S0150 is rated for continuous operation up to 50 MPa, equivalent to 7250 psi or 500 bar.
Does the pump support gradient elution?
No—the S0150 is an isocratic pump. Gradient functionality requires integration with an external low-pressure mixing module or a separate quaternary pump system.
Can the flow rate be calibrated in-house?
Yes—multi-point gravimetric calibration is supported via the onboard calibration utility, allowing users to define custom correction factors across the full 0.001–9.999 mL/min range.
Is the pump compatible with aggressive solvents such as THF or concentrated acids?
Wetted materials are chemically resistant to common HPLC solvents; however, prolonged exposure to strong oxidizers (e.g., >10% nitric acid) or halogenated solvents (e.g., chloroform) is not recommended without verifying seal compatibility.
What safety features prevent overpressure damage?
Hardware-based pressure limit enforcement, software-configurable pressure abort thresholds, and automatic flow stop upon pressure fault detection provide redundant protection for columns and fluidic components.
