(1) Inadequacy: when competitive negotiation is adopted, the purchaser directly determines two domestic manufacturers producing the laboratory instruments for negotiation.
Reason: competitive negotiation refers to that the purchaser negotiates with no less than 3 suppliers meeting corresponding qualification conditions.
(2) Improper: purchase by inquiry
Reason: government procurement projects with uniform specifications and standards, sufficient spot supply and small price changes, as well as projects other than those subject to bidding according to law, can be purchased through inquiry. In this case, it is necessary to purchase a laboratory analytical instrument with complex technology, so inquiry procurement is not suitable.
(3) Inadequacy: the inquiry document clearly stipulates the price composition of the procurement project and the criteria for evaluating the transaction.
Reason: the inquiry document or inquiry notice shall stipulate the price composition, quotation requirements and transaction evaluation standards of the procurement project.
(4) Improper: single source procurement method is adopted.
Reason: goods or services that meet one of the following circumstances may be purchased from a single source in accordance with this Law:
（1） Can only be purchased from a sole supplier;
（2） Unable to purchase from other suppliers due to unforeseen emergency;
（3） If it is necessary to ensure the consistency of the original procurement items or the requirements of supporting services, and it is necessary to continue to purchase from the original supplier, and the total amount of additional purchase funds does not exceed 10% of the original contract purchase amount.
