2. The method of claim 1, further comprising, before determining a target standard substance in a predetermined standard substance database according to the characteristic element and at least one content value corresponding to the characteristic element:

obtaining an error value of each content value in at least one content value corresponding to the characteristic element;

determining a target standard substance in a preset standard substance database according to the characteristic element and at least one content value corresponding to the characteristic element, wherein the method comprises the following steps:

and determining a target standard substance in a preset standard substance database according to the characteristic element, at least one content value corresponding to the characteristic element and the error value of each content value.

3. The method of claim 1, further comprising, after determining a target standard substance in a predetermined standard substance database according to the characteristic element and at least one content value corresponding to the characteristic element:

acquiring a first measured value of a target amount corresponding to the target standard substance;

drawing a standard working curve according to the first measured value of the target quantity and at least one content value corresponding to the characteristic element;

obtaining a second measurement value of the target quantity corresponding to the sample to be measured;

and determining the target content value of the characteristic element in the sample to be tested in the standard working curve based on the second measurement value.

4. The method of claim 3, further comprising, after determining in the standard working curve based on the second measurement value to obtain a target content value of the feature element in the sample to be tested,:

determining a target content range according to at least one content value corresponding to the characteristic element;

judging whether the target content value is within the target content range;

and when the target content value is not in the target content range, adjusting at least one content value corresponding to the characteristic element according to the target content value.

5. The method according to claim 1, wherein the standard substance database further contains at least one of a name of the standard substance, a brand of the standard substance, a number of the standard substance, a use expiration date of the standard substance, a data type of each element content value in the standard substance, and a precision level.

6. The method of claim 5, further comprising, before determining a target standard substance in a predetermined standard substance database according to the characteristic element and at least one content value corresponding to the characteristic element:

receiving updated information of the standard substance; wherein the update information of the standard substance comprises at least one of name change information of the standard substance, brand change information of the standard substance, number change information of the standard substance and deletion information when the service life of the standard substance exceeds the expiration date;

and updating the standard substance database according to the updated information of the standard substance.

7. A standard substance determination apparatus, comprising:

the characteristic element information determining module is used for determining at least one characteristic element contained in the sample to be detected and at least one content value corresponding to the characteristic element according to the sample to be detected;

the target standard substance determining module is used for determining a target standard substance in a preset standard substance database according to the characteristic elements and at least one content value corresponding to the characteristic elements; wherein, the standard substance database comprises the content value of each element in the standard substance.

8. The apparatus of claim 7, further comprising:

an error value obtaining module, configured to obtain an error value of each content value in at least one content value corresponding to the feature element before determining a target standard substance in a preset standard substance database according to the feature element and the at least one content value corresponding to the feature element;

the target standard substance determination module is configured to:

and determining a target standard substance in a preset standard substance database according to the characteristic element, at least one content value corresponding to the characteristic element and the error value of each content value.

9. A terminal, comprising:

one or more processors;

a memory for storing one or more programs,

when executed by the one or more processors, cause the one or more processors to implement the method of determining a standard substance according to any one of claims 1 to 6.
