Cornley AFT-800 Electrolyte Analyzer
The Cornley AFT-800 is a benchtop electrolyte analyzer measuring 9 parameters (K+, Na+, Cl-, Ca2+, pH, Li+, nCa, TCa, TCO2) with 70 samples/hour throughput using 65 µL serum samples. Tailored for hospitals and labs, it features ISE direct potentiometry, 2-point calibration, 7-inch touchscreen, 10,000-result storage, closed reagent kit, and barcode support for efficient, contamination-free electrolyte profiling.
Description
Electrolyte Parameters: Comprehensive Ion and Acid-Base Analysis The Cornley AFT-800 quantifies key electrolytes—potassium (K+), sodium (Na+), chloride (Cl-), ionized calcium (Ca2+), and pH—along with lithium (Li+), normalized calcium (nCa), total calcium (TCa), and total carbon dioxide (TCO2) for anion gap (AG) calculations. This panel supports rapid assessment of hydration status, acid-base balance, renal function, and cardiac risks, enabling timely interventions for conditions like hyponatremia, hyperkalemia, or metabolic acidosis in emergency, ICU, or routine lab settings.
Parameters Measured: Directly measures 6 core ions (K+, Na+, Cl-, Ca2+, Li+, pH) via ion-selective electrodes, with calculated values for nCa (temperature/pH-adjusted ionized calcium), TCa (total calcium), TCO2 (from pH and pCO2 equivalents), and AG (anion gap). Employs direct potentiometry for undiluted sample accuracy, with linearity ranges: K+ 0.3–10.0 mmol/L, Na+ 50–200 mmol/L, Cl- 50–200 mmol/L, Ca2+ 0.2–3.0 mmol/L, Li+ 0.1–3.0 mmol/L, pH 6.5–8.0; CV <1% for precision, plus alarms for critical values to flag life-threatening imbalances.
Sample Requirements: Requires 65 µL of whole blood, serum, plasma, or aqueous samples, suitable for venous or capillary collection in neonates, adults, or critical care. Supports open/closed tubes with barcode scanning for positive patient ID, minimizing errors; no dilution needed for most ranges, with auto-sampling and anti-clog probe for reliable processing in low-volume or hemolyzed specimens.
Throughput: Processes up to 70 samples per hour in continuous random-access mode, ideal for mid-sized labs or wards handling 500–1,000 tests daily. Fast 40-second TAT per sample with minimal hands-on time enables high-volume electrolyte screening during shifts, including STAT prioritization for urgent cases like post-op monitoring or dialysis patients.
Technology: Utilizes direct ion-selective electrode (ISE) potentiometry with 6 dedicated sensors (Li+, K+, Na+, Ca2+, Cl-, pH/Ref) for real-time voltage measurement against a reference electrode, ensuring sample-specific results without indirect dilution artifacts. 2-point calibration (slope and zero) with independent packs maintains accuracy over 1,000 tests per kit, while closed waste/calibration systems reduce biohazards; integrated temperature compensation (37°C) and signal processing yield stable readings in varied lab conditions.
User Interface and Storage: Equipped with a 7-inch true-color HD touchscreen for intuitive touch navigation, real-time displays of results/curves, and multilingual support (up to 6 languages, including English and Chinese). Stores 10,000 patient results with demographics, QC data, and timestamps in a searchable database; built-in thermal printer outputs customizable reports, with RS232/USB ports for LIS/HIS integration and PDF/CSV exports to facilitate electronic charting and audits.
Reagent System: Closed, maintenance-free system with joint calibration/waste kits (1,000-test capacity) and large-volume reagent bags for extended use without frequent changes. Independent packs minimize contamination risks, with on-board monitoring for low levels and auto-rinsing between samples; compatible with Cornley’s low-cost, stable solutions, reducing operational costs by 50% and supporting up to 48-hour calibration stability.
Dimensions and Portability: Compact benchtop unit measuring 280 × 320 × 380 mm (W × D × H) weighs 7 kg, fitting easily on crowded carts or counters in ERs or clinics. Low power (≤60 VA) and quiet operation (<50 dB) suit 15–30°C ambient with 30–85% humidity, with optional battery backup for 2-hour portability in mobile units.
