Five checks before supplier comparison
01
Start with the analytical method
Define the sample matrix, target analytes, method or standard, expected concentration range, throughput, and reporting requirements before comparing model names.
02
Compare the complete configuration
Confirm pumps, detectors, injectors, columns, digestion vessels, autosamplers, workstation software, accessories, consumables, voltage, plugs, and installation scope.
03
Verify documents by model
Request the English brochure, specification sheet, manual, packing list, warranty terms, and applicable compliance documents for the exact quoted model and configuration.
04
Ask for application evidence
Useful evidence connects a real sample and method to an instrument configuration. Factory photos alone do not demonstrate analytical suitability.
05
Clarify delivery and lifecycle support
Confirm lead time, packaging, Incoterms, installation, training, remote support, spare parts, consumables, software updates, and the warranty claim process.
Questions to include in an RFQ
- Which model and modules are included?
- Which method and sample matrix is the configuration intended for?
- Which accessories and consumables are required at startup?
- Which documents apply to the exact quoted model?
- What voltage, plug, installation, and training are included?
- What are the lead time, warranty, spare-parts, and support terms?
Frequently asked questions
What information should a buyer send before requesting an analytical instrument quotation?
Send the application area, sample type, target analytes or method, expected range, throughput, preferred detector, accessories, quantity, destination voltage, required documents, and delivery location.
Should analytical instruments be compared only by price?
No. Compare the complete configuration, method fit, included accessories, documentation, installation, training, warranty, consumables, spare parts, and lifecycle support. A lower base price may exclude required modules.
How can a buyer verify an instrument manufacturer?
Check the legal company identity, business address, model-specific documents, factory and production evidence, application cases, export documents, warranty terms, and whether company information is consistent across independent sources.
Does Tianzhao provide one standard configuration for every laboratory?
No. Tianzhao confirms the sample, method, throughput, detector, accessories, voltage, documents, and delivery needs before finalizing a recommended configuration and quotation.
