FAQ

What types of NSFC projects can use these experimental services?

All NSFC-funded project categories can use external laboratory services, including General Program, Young Scientists Fund, Excellent Young Scientists Fund, Key Program, Major Research Plan, Joint Fund, and Innovation Research Group projects. Services can also support grant applications by providing preliminary data.

Can the test data be used directly in journal publications and project reports?

Yes. Reports are prepared with complete methods, instrument models, test conditions, and raw data attachments so that results can be reproduced and cited in manuscripts, supporting information, and progress reports in accordance with journal data availability policies.

How is sample and data confidentiality protected?

Reputable providers sign confidentiality (non-disclosure) agreements before sample receipt, assign coded sample identifiers, restrict data access to authorized personnel, and deliver results only to the designated principal investigator or project contacts.

What is the typical turnaround time?

Routine characterization such as SEM, XRD, FTIR, and standard mechanical testing is commonly completed within three to seven working days after sample receipt. Complex multi-technique studies, sequencing projects, and custom method development may require two to eight weeks depending on scope.

How should samples be prepared and submitted?

Sample requirements vary by technique. General guidelines include providing adequate quantity for repeat measurements, ensuring sample stability during transport, packaging to avoid contamination or mechanical damage, cold-chain shipping for biological materials, and submitting a completed test request form describing sample composition, hazard status, and test objectives.

Are non-standard or custom test methods available?

Yes. Because basic research often requires novel measurement conditions, accredited third-party laboratories and university platforms offer custom protocol development, special atmosphere or temperature control, in-situ measurement setups, and combined multi-technique characterization schemes designed around the research hypothesis.

Can service fees be itemized for grant budget purposes?

Providers supply itemized testing or service lists and formal invoices that comply with research funding expenditure regulations, allowing costs to be charged to the appropriate testing and processing fee categories of the project budget.
