Real-World Testing: Putting Whatman Grade No. 3MM Chr Chromatography Paper, Cellulose, Whatman 3030-392 Sheets, Pack of 100 to the Test
First Use Experience
I initially tested the Whatman Grade No. 3MM Chr Chromatography Paper, Cellulose, Whatman 3030-392 Sheets, Pack of 100 in our forensic lab, specifically within our gas chromatography-mass spectrometry (GC-MS) suite. The testing involved separating and identifying components of a complex mixture of plasticizers, often found in improvised explosive devices. The lab environment is climate-controlled, maintaining a stable temperature and humidity to minimize external variables that could affect chromatographic results.
The paper performed admirably under controlled conditions. The solvent front moved evenly and consistently across the paper, leading to clean separation of the plasticizer components. Setting up the chromatography runs took only a matter of minutes, highlighting the ease of use associated with the well-defined paper size and consistent thickness.
The only initial “issue” was the brownish tinge to the paper when first wetted with the solvent, as mentioned in the product description. This didn’t affect the results, but it did cause a moment of slight concern until I recalled the manufacturer’s note.
Extended Use & Reliability
After several weeks of intensive use, the Whatman Grade No. 3MM Chr Chromatography Paper, Cellulose, Whatman 3030-392 Sheets, Pack of 100 continued to deliver consistent and reliable separations. We subjected the paper to various solvents and sample types, including volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). The paper held up exceptionally well, consistently providing sharp, well-defined peaks on our chromatograms.
We observed no significant signs of degradation or change in performance over time. The paper retained its structural integrity even after prolonged exposure to solvents, which is essential for quantitative analysis. Maintenance primarily involved proper storage in a dry, dark environment to prevent contamination and ensure consistent performance.
Compared to our previous experiences with cheaper chromatography papers, the Whatman paper significantly outperformed in terms of resolution and reproducibility. The consistency of the Whatman Grade No. 3MM Chr Chromatography Paper, Cellulose, Whatman 3030-392 Sheets, Pack of 100 not only saved time but also improved the accuracy of our analyses, reducing the need for repeat runs.
