The growing demand for sets of calendar dates suitable for use as calibrants
calls for high-quality records such as annually laminated lake and deep-sea sediments and ice-cores; their selection is strictly a job for specialists.

Briefly, on a log forward scatter/log side scatter dot plot, we defined the upper size limit of the microparticles using 1-[micro]m calibrant
beads and drewa gate around the population.
Obviously, the NTP carcinogenicity data must be maintained as the primary calibrant
for this study, but the data derived here for TMTU suggests that the carcinogenic profile of a chemical is not absolute (4-7,45) and that, in fact, tissue changes seen for some chemicals classified as noncarcinogenic may be predicative of an as yet unrealized, or perhaps ultimately unrealizable, carcinogenic activity.
Background fluorescence of the stop buffer droplet was recorded as a low calibrant

The quantification of the proteins depends primarily on the comparison of the measurement results with those obtained with a calibrant
The latter study investigated whether the use of the PT/INR Line from a small set of 5 ECAA calibrant
plasmas certified with manually determined INRs could reliably replace local ISI calibration.
The quality of the curve fits was assessed by back-calculating calibrant
concentrations (see online Supplemental Data 6).
CRP concentrations are routinely measured by nephelometric and turbidimetric immunoassays, in which quantification depends on comparison of the results with those obtained with a calibrant
The mass of somatropin monomer was determined by size-exclusion chromatography using CRS1 or the second WHO material as a calibrant
Furthermore, because the commercially available assays currently use synthetic or recombinant calibrant
peptides that are not glycosylated, the glycosylation of proBNP forms in vivo may adversely influence the performance of these assays.
Although these methods allow simultaneous measurement of both 25OHD3 and 25OHD2, method harmonization is limited, and there is no reference preparation or agreed calibrant
Because of the orthogonal design, a single external mass calibrant
was used to achieve better than 5 ppm mass accuracy over an entire sample plate (up to 384 samples).
