Sanotac Pilot600 Series Preparative Liquid Chromatography System / High-Pressure Preparative HPLC System with Axial Compression Capability

Overview

The Sanotac Pilot600 Series Preparative Liquid Chromatography System is a modular, high-pressure preparative HPLC platform engineered for scalable purification across research, process development, and pilot-scale manufacturing environments. Designed around dynamic axial compression (DAC) technology, the system maintains consistent column bed integrity under high backpressure—critical for reproducible separation of thermally labile, low-abundance, or structurally complex molecules. Its dual-pump architecture employs high-speed cavity pressure feedback and solvent compressibility compensation to deliver precise, pulse-minimized flow across the full operational range (0.01–600.00 mL/min), enabling robust gradient elution with up to four solvents. The integrated dual-wavelength UV-Vis detector—featuring imported deuterium and tungsten lamps—supports simultaneous monitoring at two independent wavelengths (190–800 nm), minimizing baseline drift and maximizing detection sensitivity (LOD < 0.5 mAU) and linear dynamic range (0–2 AU). This architecture ensures compliance with fundamental chromatographic principles defined in ISO 17025, USP <621>, and ICH Q5A for biomolecule purification validation.

Key Features

• Dynamic axial compression (DAC) module with real-time piston position feedback and programmable compression force control—ensuring uniform packing density and extended column lifetime during repeated loading cycles.
• Microprocessor-controlled dual-servo pump system with floating plunger design and PEEK or 316L stainless steel wetted parts—optimized for chemical resistance, low pulsation (<0.2 MPa), and long-term seal durability at pressures up to 10 MPa.
• Advanced flow calibration using multi-point correction curves across the entire flow range—guaranteeing ±0.5% volumetric accuracy independent of solvent viscosity or compressibility.
• Dual-wavelength photometric detection with wavelength-programmable time schedules, stop-flow spectral scanning, and automatic lamp switching—reducing downtime and improving quantitative reliability for co-eluting analytes.
• Modular fraction collection interface supporting timed, peak-triggered, or UV-threshold-based collection—compatible with both stainless steel and high-pressure borosilicate glass columns (up to 100 mm ID).
• Regulatory-compliant software platform certified for 21 CFR Part 11 and CFDA GxP requirements—including electronic signatures, audit trails, user access levels, and method versioning.

Sample Compatibility & Compliance

The Pilot600 accommodates diverse sample matrices without modification: crude botanical extracts, synthetic organic intermediates, oligonucleotides, monoclonal antibody fragments, and post-translational modified peptides. Its solvent compatibility spans water, acetonitrile, methanol, THF, DCM, and acidic/basic modifiers—validated per ASTM D4790 for pump corrosion resistance. Column hardware interfaces conform to ISO 8503-2 surface finish standards for high-pressure fittings. All electronic subsystems meet IEC 61000-4 electromagnetic compatibility requirements. System qualification documentation supports IQ/OQ/PQ protocols aligned with WHO TRS 986 Annex 4 and EU GMP Annex 15 for analytical and preparative chromatographic equipment.

Software & Data Management

Control and data acquisition are managed through a Windows-native workstation application supporting method development, sequence scheduling, real-time chromatogram overlay, and automated report generation. Raw data files adhere to ANDI/NetCDF format for third-party integration (e.g., Empower, Chromeleon). Audit trail records capture all parameter changes, user logins, method executions, and fraction collection events—with immutable timestamps and digital signatures. Electronic record retention complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), satisfying inspection readiness for FDA pre-approval inspections and MHRA GMP audits.

Applications

• Purification of natural product isolates (e.g., ginsenosides, curcuminoids, paclitaxel analogs) from plant extracts using reversed-phase or normal-phase DAC columns.
• Process-scale desalting and buffer exchange of recombinant proteins prior to formulation—leveraging low-pressure silica-based media compatible with the system’s 10 MPa ceiling.
• Chiral resolution of enantiomeric drug candidates via polysaccharide-based chiral stationary phases under SFC-compatible conditions (with CO₂ pump add-on).
• Removal of synthesis by-products and residual catalysts from small-molecule APIs—validated per ICH Q3A(R2) impurity profiling guidelines.
• Preparative isolation of mRNA-LNP intermediates requiring sterile-grade filtration and endotoxin-free handling—supported by optional bio-inert fluidic path upgrades.

FAQ

Does the Pilot600 support method transfer from analytical to preparative scale?
Yes—the system implements identical dwell volume compensation algorithms and gradient delay modeling as Sanotac’s analytical HPLC platforms, enabling direct scaling using constant linear velocity or constant mass load principles.
Can the DAC module be retrofitted to existing columns?
No—the axial compression assembly is integrated into the column housing and requires factory calibration; however, Sanotac offers column rebuild services with DAC-ready cartridges for legacy systems.
Is the software validated for GMP production environments?
The standard software package includes full 21 CFR Part 11 validation documentation (URS, FRS, IQ/OQ/PQ protocols, traceability matrix), with optional on-site installation qualification support.
What is the maximum column internal diameter supported?
The standard configuration accommodates columns up to 100 mm ID; custom manifolds are available for 150 mm ID applications upon engineering review.
How often does the UV lamp require replacement?
Deuterium lamps maintain stable output for ≥2,000 hours; tungsten lamps exceed 5,000 hours—both monitored automatically via intensity tracking and logged in the audit trail.
