Product Overview
N-Methyl Pyrrolidone (NMP) in GC HS grade represents the highest purity standard for analytical applications requiring ultra-low background interference. This solvent is meticulously distilled and tested to meet headspace gas chromatography specifications, ensuring minimal impurity peaks that could compromise sensitive residual analysis. The product’s exceptional solvent power and thermal stability make it particularly suitable for extracting and analyzing trace-level contaminants in complex matrices. Its low volatility and high boiling point (202°C) provide consistent performance across extended analytical runs. The GC HS grade undergoes rigorous quality control, including GC-MS validation, to guarantee batch-to-batch consistency. This formulation maintains optimal viscosity characteristics while eliminating common GC contaminants like phthalates or plasticizers that could interfere with baseline stability. The solvent’s hygroscopic nature is carefully controlled during packaging to prevent moisture absorption that could affect analytical results. Each batch comes with comprehensive certification documentation detailing impurity profiles and retention time verification data for quality assurance.
FAQs
1. What makes this NMP grade different from standard laboratory grades?
This GC HS grade undergoes additional purification steps specifically to remove volatile impurities that could appear as false positives in headspace analysis, with strict limits on residual solvents and plasticizers.
2. Can this solvent be used with automated headspace samplers?
The low viscosity and consistent composition make it fully compatible with automated headspace systems, with no risk of needle clogging or carryover between samples.
3. What’s the typical shelf life for unopened containers?
When stored in original sealed containers at room temperature, the product maintains its specifications for 24 months from the date of manufacture.
4. Are there any special storage requirements after opening?
After opening, store in tightly sealed glass containers with minimal headspace, protected from light and moisture to prevent contamination or degradation.
5. How does the purity compare to HPLC grade NMP?
GC HS grade has stricter controls on volatile impurities and lower UV absorbance than HPLC grade, though both meet high purity standards for their respective applications.
