Product: Ascentis Express Phenyl-Hexyl Uses: Chromatography column packing material, optimized for analytical separations in various lab environments Appearance: Fine solid powder, off-white to light tan in color Odor: None noticeable Main Components: Porous silica particles chemically bonded with phenyl-hexyl functional groups
Physical Risk: Inhalable dust can irritate breathing passages Exposure Route: Lung, eye, skin contact through mishandling or cleaning Label Status: Not classified as hazardous under GHS for finished bonded phase Symptoms: Eye irritation, coughing, sneezing if airborne particles enter the respiratory tract
Silica (amorphous): Bulk of the column packing, forms most of the powder Phenyl-hexyl modification: Covalently bound, gives the medium its chromatographic selectivity Impurities: Minimal, limited to trace process reagents, no added solvents
Eye Contact: Rinse eyes gently with water for several minutes, remove contact lenses Inhalation: Move outdoors for fresh air, get medical attention if breathing feels tight Skin Contact: Remove dust with mild soap and water Ingestion: Rinse mouth with water, avoid inducing vomiting
Flammability: Not flammable, but packaging burns easily Combustion Byproducts: Silica ash, carbon oxides if organic groups burn Suitable Extinguishing Media: Water spray, CO2, dry chemical Special Equipment: Masks, eye protection in heavy smoke
Containment: Scoop solid carefully to prevent dust spread Cleanup: Use wet methods or HEPA vacuum, avoid brooms or dry sweeping Disposal: Place in labelled, approved waste container Environmental Note: Avoid drain disposal
Handling: Minimize dust, avoid spills, work in ventilated space Storage: Keep in tightly closed container, room temperature, away from direct sunlight and moisture Segregation: Do not store with food, drink, or incompatible chemicals
Eye Protection: Safety glasses recommended during handling Respiratory Protection: NIOSH-approved mask or respirator with fine particulate filter Gloves: Nitrile or latex gloves for skin barrier Ventilation: Laboratory fume hood or localized exhaust
Physical State: Solid, micro- or nano-scale powder Color: Off-white to pale tan Molecular Structure: Silica backbone with attached hydrophobic phenyl-hexyl ligands Solubility: Practically insoluble in water Threshold Odor: None
Thermal Stability: Stable under recommended storage and use Reactive Incompatibilities: Strong acids or alkalis can degrade silica Hazardous Byproducts: None known under normal conditions Polymerization: Not expected
Acute Toxicity: Low, may irritate lungs and eyes due to particulate nature Chronic Exposure: Long-term inhalation of silica dust linked to respiratory issues in industrial or mining settings; this material is more inert Sensitization: No documented skin or lung sensitizers
Mobility in Soil: Low, as bonded silica tends to stay where it lands Persistence: Not biodegradable, remains as inert mineral Aquatic Toxicity: Minimal concern, not water-soluble nor acutely toxic in environmental quantities
Procedure: Package unused or spilled solid in sealed, labeled containers Local Rules: Follow local hazardous waste legislation or lab protocols Eco-sensitivity: Avoid landfill if spills include solvents or other reagents
UN Number: Not regulated for transport as a hazardous material Packing Instructions: Use strong containers, seal to prevent leaks, cushion as powder can shift Labeling: Avoid food containers, mark as lab chemical
Safety Status: Not subject to major chemical restriction regulations for silica-bound phases Workplace Limits: General OSHA respirable dust rules apply in the US, stricter exposure limits in some countries Labelling: Provide clear hazard communication in shared spaces
