Laballiance HPLC 1500 Series Isocratic High-Performance Liquid Chromatography System

Overview

The Laballiance HPLC 1500 Series Isocratic High-Performance Liquid Chromatography System is a robust, entry-level analytical platform engineered for precision, reliability, and operational simplicity in routine laboratory environments. Built upon proven single-piston pump architecture and optimized fluidic design, the system delivers stable solvent delivery and low-pressure pulsation—critical for compatibility with sensitive detection modalities including electrochemical (EC) and refractive index (RI) detectors. Its isocratic configuration comprises a Laballiance Model III high-pressure solvent delivery pump and a Model 201 variable-wavelength UV-Vis absorbance detector, both designed to meet fundamental chromatographic performance requirements without compromising mechanical integrity or long-term stability. The system operates on classical reversed-phase, normal-phase, and ion-exchange separation principles, supporting method development, quality control release testing, and stability-indicating assays across pharmaceutical, environmental, food safety, and academic research laboratories.

Key Features

• Single-piston Model III pump with integrated low-volume diaphragm pulse damper and fast-fill cam mechanism—ensuring baseline stability <0.5 mAU and pressure pulsation <0.2% RMS.
• Model 201 UV-Vis detector featuring dual-lamp source (deuterium + tungsten), programmable wavelength selection (190–800 nm), and real-time baseline zeroing via front-panel controls or remote software command.
• Dual flow rate ranges (0.001–5 mL/min and 0.01–10 mL/min) accommodate narrow-bore, standard, and semi-preparative column formats with consistent accuracy (±1%) and exceptional reproducibility (≤0.075% RSD).
• Modular architecture allows seamless upgrade to binary gradient operation by adding a second Model III pump and low-dead-volume mixing tee—no hardware replacement or firmware reconfiguration required.
• Standard wetted path options include 316 stainless steel and biocompatible PEEK—both supplied at no additional cost, enabling direct use with acidic, basic, or proteinaceous mobile phases.
• Front-panel keypad interface supports standalone method setup; full instrument control and data acquisition are enabled via optional PC-based chromatography data system (CDS) compliant with ASTM E2524 and ISO/IEC 17025 workflows.

Sample Compatibility & Compliance

The HPLC 1500 Series accommodates a broad range of sample matrices—including small-molecule APIs, organic acids, amino acids, carbohydrates, and natural product extracts—when paired with commercially available reversed-phase (C8, C18), HILIC, or ion-pairing columns (2.1–4.6 mm i.d., 50–250 mm length). All fluidic components conform to USP Class VI biocompatibility standards where PEEK is specified. The system meets mechanical and electrical safety requirements per UL 61010-1 and IEC 61010-1. When operated with validated CDS software, it supports audit trails, electronic signatures, and data integrity practices aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations for regulated environments.

Software & Data Management

Instrument control and data acquisition are supported through third-party chromatography data systems (e.g., Chromeleon, Empower, OpenLab CDS) or custom LabVIEW-based interfaces. Raw analog output (0–1 V DC) and digital TTL trigger signals enable integration with external integrators, fraction collectors, or mass spectrometers. All detector signals are digitized at ≥20 Hz sampling rate, with 24-bit ADC resolution ensuring linear dynamic range >2.5 AU. Method files store complete acquisition parameters—including flow program, wavelength schedule, and detector gain—enabling full traceability and reprocessing capability per GLP/GMP documentation standards.

Applications

• Pharmaceutical QC testing: assay quantitation of active ingredients per USP monographs using isocratic elution.
• Environmental analysis: determination of phenolic compounds, PAHs, and pesticides in water extracts per EPA Method 8330B.
• Food and beverage quality assurance: caffeine, preservatives, and artificial colorants profiling in soft drinks and dairy products.
• Academic teaching labs: hands-on instruction in retention time prediction, selectivity optimization, and detector response linearity assessment.
• Biotechnology support: purity evaluation of synthetic peptides and oligonucleotides under mild aqueous conditions using PEEK-flow-path configurations.

FAQ

Can the HPLC 1500 be upgraded to gradient operation after purchase?
Yes—the system supports field-upgrade to binary gradient mode by installing a second Model III pump and low-dead-volume mixer. No controller replacement or firmware update is required.
Is the Model 201 detector compatible with post-column derivatization setups?
Yes—its analog output and TTL-compatible event triggering support synchronization with reaction coils and auxiliary reagent pumps.
What validation documentation is provided with the system?
Each unit ships with Factory Acceptance Test (FAT) report, pump flow accuracy verification certificate, and detector wavelength calibration record traceable to NIST SRM 2034.
Does Laballiance offer IQ/OQ services for this system?
Yes—qualified installation and operational qualification protocols are available upon request and may be executed by certified field service engineers.
Are replacement parts and consumables stocked in North America?
All critical spares—including pump seals, detector lamps, and injection valve rotors—are maintained in Laballiance’s Pennsylvania distribution center with standard lead time ≤3 business days.
