Sanotac AP-0013 PEEK High-Pressure Binary LC Pump

Overview

The Sanotac AP-0013 is a high-precision, PEEK-head binary high-pressure liquid chromatography (HPLC) pump engineered for demanding analytical and preparative applications in ion chromatography (IC), liquid chromatography (LC), gel permeation chromatography (GPC), post-column derivatization systems, hyphenated techniques such as HPLC-AFS (atomic fluorescence spectrometry), and clinical diagnostic instrumentation—including HbA1c analyzers, amino acid analyzers, and IVD platforms. Its core architecture employs a dual-piston, serially coupled plunger system with floating plunger design—optimized to minimize mechanical hysteresis and deliver exceptional long-term stability under sustained pressure loads up to 30 MPa. The pump operates on positive displacement principle, utilizing precision-machined PEEK pump heads, sapphire-ruby check valves, and chemically inert flow path materials (PEEK, PTFE, ceramic) to ensure compatibility with aggressive mobile phases including strong acids, bases, and organic solvents commonly used in IC and trace metal analysis.

Key Features

• High-fidelity flow delivery across full range: 0.001–9.999 mL/min with 0.001 mL/min resolution and ±0.1% absolute accuracy (certified per ISO 5725-based validation protocols)
• Low-pressure pulsation design: ≤0.1 MPa peak-to-peak variation achieved via cam-profile compensation and real-time electronic pulse suppression circuitry
• Integrated column protection logic: programmable upper pressure limit, zero-point offset calibration, and environmental drift compensation algorithms
• Dual-mode plunger cleaning: automated post-stroke solvent flush to reduce seal wear and extend service life beyond 10,000 hours of continuous operation
• Modular I/O architecture: native support for analog voltage input (0–5 V / 0–10 V), digital TTL start/stop, and configurable relay outputs for process integration
• Multi-protocol communication stack: standard RS232 and USB interfaces; optional RS485/RS422; protocol support includes Sanotac proprietary command set, Modbus RTU/ASCII, and industrial fieldbus-ready configuration

Sample Compatibility & Compliance

The AP-0013 is designed for use with aqueous eluents, organic modifiers, and mixed-phase mobile phases typical in suppressed and non-suppressed ion chromatography methods (e.g., ASTM D4327, ISO 10304-1, USP ). All wetted components comply with USP Class VI biocompatibility requirements and meet RoHS Directive 2011/65/EU restrictions on hazardous substances. The pump’s pressure control loop and flow calibration routines are traceable to NIST-traceable flow standards, enabling compliance with GLP and GMP documentation requirements. When integrated into regulated environments, the firmware supports audit trail generation (per FDA 21 CFR Part 11 Annex 11 principles) when paired with validated third-party data acquisition software.

Software & Data Management

The AP-0013 supports both embedded and host-based control paradigms. Onboard firmware enables local method execution—including constant, linear gradient, and multi-step flow programs—with real-time visualization of pressure vs. time and flow rate vs. time curves on the 256×64 backlit LCD. Data logging captures timestamped pressure and flow readings at user-defined intervals (10 ms–10 s), exportable as CSV or Excel-compatible XLSX files with embedded metadata (method ID, operator, calibration date). Remote operation is enabled via optional PC-based control suite supporting SCADA/DCS integration through OPC UA or Modbus TCP gateways. All calibration parameters—including volumetric correction factors per flow segment—are stored in non-volatile memory and can be restored to factory defaults or reloaded from secure backup files.

Applications

• Ion chromatography systems requiring stable, low-pulse eluent delivery for conductivity detection of anions (F⁻, Cl⁻, NO₃⁻, SO₄²⁻) and cations (Na⁺, NH₄⁺, K⁺, Ca²⁺, Mg²⁺)
• Preparative-scale LC purification where reproducible flow profiles impact fraction purity and yield consistency
• Column post-derivatization modules demanding precise reagent metering synchronized with detector response windows
• Automated sample preparation workflows in clinical labs—including glycohemoglobin (HbA1c) quantification and amino acid profiling per CLSI EP10-A3 guidelines
• Process analytical technology (PAT) deployments integrating pump control into closed-loop reactor feed systems using gravimetric feedback

FAQ

What mobile phase chemistries is the AP-0013 compatible with?
The PEEK, sapphire, ruby, and ceramic wetted path ensures compatibility with pH 0–14 aqueous buffers, 100% acetonitrile/methanol, and common IC eluents such as KOH, NaOH, and methanesulfonic acid solutions.
Does the pump support gradient mixing?
The AP-0013 is a binary high-pressure pump; gradient formation requires external low-pressure mixing or integration with a compatible quaternary solvent selection valve (not included).
Is remote firmware update supported?
Yes—via USB or RS232 using Sanotac’s certified firmware update utility, with checksum verification and rollback capability.
Can the pump be integrated into a PLC-controlled manufacturing line?
Yes—through discrete I/O signals and Modbus RTU over RS485, enabling full status monitoring and setpoint control within Siemens S7, Rockwell ControlLogix, or Beckhoff TwinCAT environments.
What calibration documentation is provided?
Each unit ships with a factory calibration certificate listing flow accuracy and pressure linearity test points at 1, 5, and 10 mL/min, referenced to ISO/IEC 17025-accredited flow standards.
