Product Name – n-BUTANOL 99.9% GC Quantity/Pack Size – 250 ml Form – Liquid Grade – GC (Gas Chromatography) Application – GC analysis, residue-free solvent applications, trace analysis

Product Overview

n-Butanol 99.9% GC is an ultra-high-purity solvent specifically designed for gas chromatography and other trace-level analytical techniques. Its exceptional purity minimizes baseline noise and ghost peaks, ensuring accurate detection of volatile and semi-volatile compounds. The solvent’s low residue profile prevents column contamination, extending the lifespan of GC systems. This grade is also ideal for applications requiring minimal interference, such as environmental testing, food analysis, and pharmaceutical research. The rigorous distillation and filtration processes eliminate trace impurities, including aldehydes, ketones, and water, which could compromise analytical results. For optimal performance, store in a cool, dry place and use amber glass bottles to prevent photo-degradation.

FAQs

1. Why is GC-grade n-Butanol preferred for environmental testing?

Its ultra-low impurity levels prevent false positives in trace analysis, critical for detecting pollutants at ppb/ppm concentrations.

2. Can this grade be used for headspace GC?

Yes, its high purity and low volatility make it suitable for headspace analysis of volatile organic compounds (VOCs).

3. What is the maximum allowable water content in GC-grade n-Butanol?

GC-grade n-Butanol typically contains less than 0.05% water, ensuring compatibility with moisture-sensitive detectors like FID or MS.

4. Does this solvent require filtration before GC use?

While pre-filtered, additional filtration through a 0.2 µm membrane is recommended if particulate contamination is a concern.

5. How does GC-grade n-Butanol compare to HPLC-grade?

GC-grade prioritizes volatility and minimal residue, while HPLC-grade focuses on UV transparency and gradient compatibility.
