<h3>Overview</h3>
<p><strong>QuEChERS</strong> (Quick, Easy, Cheap, Effective, Rugged, and Safe) is a standardized sample preparation technique for multi-residue analysis. It utilizes buffered salts and dispersive solid-phase extraction (d-SPE) to isolate analytes from complex matrices like fruits, vegetables, and grains.</p>
<h3>Application</h3>
<ul>
<li><strong>Industries:</strong> Food safety testing, environmental monitoring, and agricultural residue control.</li>
<li><strong>Equipment:</strong> High-performance liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS).</li>
</ul>
<h3>Precautions</h3>
<ul>
<li><strong>Environment:</strong> Store desiccants at 15-25°C with humidity below 40%.</li>
<li><strong>Operation:</strong> Maintain centrifuge speeds between 3000-6000 rpm; avoid pressure fluctuations during extraction.</li>
<li><strong>Maintenance:</strong> Calibrate scales weekly and replace d-SPE sorbents after single-use cycles.</li>
</ul>
