Consider the effective dilution factor of your spike (assuming the whole spike passed through the cartridge and was collected with the eluent.) this is equivalent to one of your calibration standards. compare the average spike addition signals for each analyte to the peak areas from the appropriate calibration standard. what % of the added spike was detected? (this is the % recovery through the spe cartridge).

they must be certified by the avma. ( a.)

mark me the branliest.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

it's c (engineer's do their work with mechanical stuff not on any living being)
