❓ Frequently Asked Questions

Q: What is the minimum order quantity (MOQ) for the AA320N series?
A: 1 unit is available for testing and evaluation. Volume discounts are available for multiple units.

Q: What is the typical delivery time?
A: In-stock instruments ship within 1-3 days from our logistics center in Asia via DHL/FedEx/UPS. Delivery to most countries takes 2-4 business days after dispatch.

Q: Do you provide installation and training?
A: Yes, we provide remote installation support and can arrange on-site training for qualified partners.

Q: What is the warranty period?
A: All AA320N series spectrophotometers come with a 12-month warranty against manufacturing defects.

Q: What is the difference between flame, graphite furnace, and hydride generation modes?
A: Flame mode is suitable for routine analysis of most elements. Graphite furnace mode offers higher sensitivity for trace analysis. Hydride generation is specifically for elements like As, Se, and Hg that form volatile hydrides.
