Sentence examples for undiluted matrix from inspiring English sources
RA was very similar to SSE in undiluted matrix solution.
Matrix effects were determined by adding stock solution after extraction of blank mock samples to obtain 300 μg L−1 per toxin in undiluted matrix solution as well as in 1 + 9 (v/ v) and 1 + 49 (v/ v) dilutions (diluted with ACN/H2O 1 + 1 (v/ v)).
