Sample Preparation Instrument

Orun’s sample preparation equipment provides robust solutions for the essential first step in any analytical workflow: converting raw or complex samples into a clean, analyte‑ready form suitable for chromatography, spectrometry, or other laboratory analyses.

Sample preparation refers to the series of actions taken to transform a sample from its original state to a form that is suitable for analysis in a laboratory setting. The exact process can vary widely depending on the type of sample and the analysis to be performed. However, the main goal of sample preparation is to isolate the desired analytes (the components of interest) from the sample matrix (the bulk of the material), remove any contaminants or interfering substances, and convert the analytes into a form that is compatible with the analytical technique to be used.

Why Sample Preparation Matters

Before analysis, samples often contain interfering matrix components — solids, particles, suspended matter, complex mixtures, or unwanted compounds — that can obstruct separation columns, compromise detectors, distort results, or reduce instrument lifetime. Proper sample preparation helps to: isolate the target analytes, remove interferences, concentrate or purify the analytes, and ensure compatibility with the analysis method. 

Without effective cleanup and preparation, even the best analytical instruments may produce inaccurate, irreproducible, or unreliable data. 

Sample preparation steps

1. Sampling / Subsampling: Collect a representative portion to ensure accurate analysis.

2. Drying / Embrittlement: Dry or embrittle sticky or elastic samples to facilitate grinding.

3. Cleanup / Sieving: Remove interfering substances using techniques like chromatography or selective adsorbents.

4. Size Reduction / Homogenization: Grind or crush solid samples to reduce particle size and improve analyte accessibility.

5. Extraction: Separate analytes from the sample matrix using an Extractor, such as solvent extraction or solid-phase extraction. Orunsci’s automated Extractors improve efficiency and recovery while minimizing manual work.

6. Concentration: Reduce sample volume to increase analyte concentration using a Concentrator, such as evaporation, centrifugation, or filtration. Orunsci’s nitrogen blowdown Concentrators provide fast and controlled concentration to prevent analyte loss.

7. Derivatization: Chemically modify analytes when needed to enhance volatility or detectability, especially for gas chromatography.

8. Transfer to Analysis Vessel: Move the prepared sample into a container suitable for analysis, like a chromatography vial or autosampler tube.
