Skalar SAN++ Continuous Flow Analyzer (CFA) – Refurbished Industrial-Grade Wet Chemistry Analyzer

Overview

The Skalar SAN++ Continuous Flow Analyzer (CFA) is a modular, laboratory-grade wet chemistry platform engineered for high-throughput, trace-level quantitative analysis of liquid and digested solid samples. Based on the segmented flow analysis (SFA) principle—where discrete sample segments are separated by air bubbles in a continuous carrier stream—the SAN++ enables precise reagent addition, controlled reaction timing, thermal management, and optical detection under reproducible hydrodynamic conditions. Unlike discrete analyzers, the SAN++ maintains constant flow dynamics across all channels, ensuring exceptional inter-day and intra-run precision (RSD < 1.5% typical for NH₄⁺, NO₃⁻, PO₄³⁻). Its architecture supports 24/7 unattended operation with full system autonomy, including automated startup, sample queueing, dilution, calibration, and shutdown—making it suitable for regulated environments requiring GLP/GMP-compliant data integrity.

Key Features

• Modular reactor manifold supporting up to four independent chemical processing units under single software control
• Temperature-controlled reaction zones: heating from ambient to +180 °C (via Peltier or resistive heaters) and cooling to −40 °C (via recirculating chiller)
• Integrated online sample pretreatment modules: digestion (microwave- or block-heated), distillation (standard, high-enrichment, vacuum tail-gas absorption, all-metal alkaline), dialysis, solvent extraction, and ion exchange
• Dual-beam digital photometer with automatic background correction: simultaneous measurement at primary and reference wavelengths (e.g., 540 nm / 700 nm) to compensate for turbidity, color, or matrix absorbance
• Configurable flow cells: 5–50 mm pathlength standard cells; optional 1–5 m fiber-optic flow cells for sub-ppb sensitivity (e.g., seawater NO₂⁻, phenols, PO₄³⁻)
• 24-bit ADC with software-adjustable baseline and gain; LED or tungsten-halogen light sources per channel; light-tight detector housing
• Auto-dilution module: pre- and post-analysis dilution of out-of-range samples; automated preparation of multi-point calibration standards

Sample Compatibility & Compliance

The SAN++ accepts aqueous extracts, acid digests, enzymatic hydrolysates, and clarified biological fluids. It accommodates matrices ranging from ultrapure water and seawater to wastewater, soil leachates, plant digests, beer wort, tobacco homogenates, and petroleum distillates. All hardware and software components comply with international method standards—including EPA Methods 300.0, 353.2, 4500-NH₃ F, 4500-NO₂⁻ B; ISO 11905-1 (total nitrogen), ISO 6878 (phosphorus); CEN EN 15962 (beer analysis); ASBC Beer-1 (diacetyl), Beer-2 (free amino nitrogen); and CORESTA Recommended Methods for tobacco. The system meets FDA 21 CFR Part 11 requirements via FlowAccess™ software, providing electronic signatures, audit trails, role-based access control, and immutable data archiving.

Software & Data Management

FlowAccess™ is a Windows-native application built on Microsoft .NET Framework, delivering full instrument orchestration—from autosampler positioning and peristaltic pump sequencing to detector synchronization and real-time QC flagging. It implements CLP (Chemical Laboratory Practice) and QC protocols per ISO/IEC 17025, including LIMS-ready data export (CSV, XML, Excel), customizable report templates, and automated pass/fail evaluation against user-defined control limits. Audit trails record every parameter change, sample injection, calibration event, and user login with timestamp and operator ID. Raw signal traces, peak integration parameters, and calibration curves are stored with metadata for full traceability. Data can be exported directly to enterprise LIMS or ELN systems without manual reformatting.

Applications

The SAN++ serves as a core analytical platform across environmental, food & beverage, agricultural, and industrial quality control laboratories. In environmental labs, it quantifies total cyanide (EPA 414.3), volatile phenols (EPA 420.1), anionic surfactants (ISO 7875-2), total phosphorus (ISO 6878), and combined nitrate/nitrite (ISO 14911). Food testing applications include total sulfur dioxide (AOAC 990.25), vitamin C (AOAC 967.22), reducing sugars (AOAC 982.14), and starch (AOAC 975.20). Brewing and winemaking labs rely on it for diacetyl (ASBC Beer-1), free amino nitrogen (FAN), α-amylase activity, and SO₂ speciation. Tobacco analysis covers nicotine (CORESTA RM 12), chloride, and nitrate. Soil and fertilizer testing includes ammonium, total Kjeldahl nitrogen, orthophosphate, and sulfate.

FAQ
