The phrase "a ods" is not correct in English.
Did you mean "an odd"? If this is the case, you can use it when referring to something unusual or strange.
Example: "It was an odd experience to see the cat walking on its hind legs."
Alternatives: "a peculiar" or "an unusual".
column connected to a ODS precolumn used at room temperature.
colomn connected to a ODS pre-column used at room temperature with a flow rate of 5 mL min−1.
Briefly, PSP toxins were separated by ion-pair chromatography on a ODS reverse-phase analytical column and detected fluorometrically after post-column derivatization.
The chromatographic separation was performed with solvent proportion of 37 : 63 using a ODS HYPERSIL column (4.6 × 250 mm, 5 μM) with 1.25 mL·min−1 flow rate with 10 μL sample injection volume.
Analyses were performed on a Shim-pack VP-DOS C18 analytical column (250 mm×4.6 mm i.d., particle size 5 μm, Shimadzu, Kyoto, Japan), which was protected by a ODS guard column (Security Guard, Phenomenex®, USA) at 30 °C.
At 525 nm, data appear linear for the MWL-AUC and the XL-A up to an OD of 1.5.
Samples were required to have a RIN >6.5, an OD 260∶280 of 1.9 2.1, an OD 260/230 >1.5 and >1.5 28S:18S ratio of the ribosomal bands for gene expression array analysis.
Optical densities (OD) were determined using the manufacturer's guidelines at 450 and 630 nm; a positive result was determined by an OD ≥0.1 and a negative result by an OD <0.1.
By Illumina criteria, RNA samples for gene expression array analysis were required to have a RIN > 7, an OD 260 280 of 1.9-2.0, an OD 260/230 of > 1.8 and a 28S:18S ratio of the ribosomal bands of > 1.5.
Sometimes you don't know if it's an OD or a nap, nodding out to the point of unconsciousness.
A sample showing an OD value >2.1 times the P/N ratio was considered positive.
