Key Features

• Enhanced Baseline Stability: The LC1620B system introduces a redesigned electronic shielding and optical path that significantly cuts down background noise, allowing the detection of trace components.

• Auto-Protection System: Features intelligent over-pressure limits, low-pressure leakage protection, and automated solvent level warning indicators to prevent dry running.

• Precise Gradient Elution: Supports high-pressure binary or low-pressure quaternary gradient configurations, enabling fast separation of highly complex samples.

• Intelligent Data Software: Accompanied by user-friendly chromatography software that handles instrument control, peak integration, quantitative report generation, and data security compliance.

Primary Applications

• Pharmaceuticals and Biotechnology: Content uniformity testing, drug stability assays, impurity profiling, and separation of active pharmaceutical ingredients (APIs).

• Food and Consumer Safety: Rigorous testing for illegal food dyes, chemical preservatives, microcystins, and residual veterinary drugs in meats.

• Environmental Monitoring: Detection of phenols, polycyclic aromatic hydrocarbons (PAHs), and modern chemical pollutants in industrial wastewater.

• Cosmetics and Chemical Industry: Analyzing raw chemical ingredients, essential oils, organic pigments, and personal care formulations.
