Product Overview
The Lead Acetate Reagent Strips (Ph. Eur. grade) are designed for rapid, on-the-spot qualitative analysis in laboratory settings. Each strip is impregnated with high-purity lead acetate, which reacts with target anions to form characteristic precipitates—black with sulfides, white with sulfates, and colored complexes with halides. The Ph. Eur. compliance ensures consistent sensitivity and minimal interference, making these strips ideal for preliminary screening or educational demonstrations. The dry format eliminates the need for liquid reagent preparation, reducing contamination risks and simplifying workflows. Strips are individually sealed to maintain stability and are compatible with standard lab protocols. For optimal performance, store in a cool, dry environment away from direct sunlight and volatile chemicals. Note: Not for quantitative analysis; intended solely for qualitative identification.
FAQs
1. How do lead acetate strips detect sulfides compared to other anions?
The strips turn black in the presence of sulfides due to lead sulfide formation, while sulfates produce a white lead sulfate precipitate. Halides may yield faint colored deposits depending on concentration.
2. Can these strips be used with acidic or alkaline samples?
Neutral pH (6–8) is recommended for accurate results. Highly acidic or alkaline samples may dissolve the lead acetate coating or alter reaction visibility.
3. What is the shelf life of unopened lead acetate strips?
When stored in original packaging at 15–25°C, the strips retain efficacy for 24 months from the manufacturing date. Avoid exposure to moisture or ammonia fumes.
4. Are there alternatives for detecting sulfides without lead-based reagents?
Silver nitrate strips or sodium nitroprusside solutions can detect sulfides, but lead acetate offers higher specificity for low-concentration samples in qualitative tests.
5. Do these strips require calibration before use?
No calibration is needed. However, testing a known negative control (e.g., deionized water) is advised to confirm strip integrity before analyzing samples.
