The integrated nanoliter system is a measuring, separating, and mixing device that is able to measure fluids to the nanoliter, ...
This is necessary since the signal-to-noise ratio of sample sizes in the microliter to nanoliter range is dramatically reduced compared to bench-scale sample sizes, and microcoils have been shown to resolve this issue. [84] Mass spectrometry (MS) and high-performance liquid chromatography (HPLC) have also been used to overcome this challenge.

The two primary methods of ionization for mass analysis used in droplet-based microfluidics today are matrix-assisted laser desorption/ionization [241] [242] and electrospray ionization . [63] Additional methods for coupling, such as (but not limited to) surface acoustic wave nebulization ( SAWN ), [ 243 ] and paper-spray ionization onto ...
Lambda (written λ, in lowercase) is a non-SI unit of volume equal to 10 −9 m 3, 1 cubic millimetre (mm 3) or 1 microlitre (μL).Introduced by the BIPM in 1880, [1] the lambda has been used in chemistry [2] and in law for measuring volume, but its use is not recommended.

This method is more expensive than the more common gravimetric method, given the cost of the colored reagents, and is recommended when optimal accuracy is required. It is also recommended for extremely low-volume pipette calibration, in the 2 microliter range, because the inherent uncertainties of the gravimetric method, performed with standard ...
The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [1]1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method.
