The phrase "amount of sample required" is correct and usable in written English.
It can be used in contexts where you need to specify the quantity of a sample needed for analysis or testing.
Example: "Before we proceed with the experiment, we need to determine the amount of sample required for accurate results."
Alternatives: "quantity of sample needed" or "sample size necessary".
This approach minimizes sampling errors, the amount of sample required for each analysis and the requirements and costs of assay reagents.
Although the dIVT protocol is less sensitive than the IVT (a 10% loss of detection in the number of genes whose expression levels could be measured), the requirement of much lesser amount of sample required for dIVT protocol (20 100 times less than IVT protocol), makes it a highly desirable methodology for target preparation, when sample amounts are limiting.
The amount of sample required for analysis in MIR was 1 mL.
Also, the amount of sample required for the identification of pathogens is much less than that required for biochemical assays.
However, these methodologies are limited due to the difficulty in achieving accurate results, the complexities in their theoretical model and the amount of sample required for measurements.
Electrochemical microfluidic devices have advantages in that the amount of sample required is small, the measurement throughput is high, different functions can be integrated on a single device, and they are highly durable.
Furthermore, it is desirable to assemble a data set from as few diffraction images as possible, since the potential of XFELs has been limited by the very large amounts of sample required for the Monte Carlo method, compounded by severe limitations in the availability of beamtime.
In addition, they are fast and simple, and the amount of sampling required to achieve a desired precision is calculable.
The amount of sampling required, in terms of both the number of images and number of points, varies with the abundance, size and distributional pattern of target biota.
Despite being formally exact with the Chemical Master Equation (CME), in practice, this approach turns out to be computationally expensive mainly due to the considerable amount of sampling required to compute reliable statistical averages.
Miniaturized microdevices have various advantages in terms of functions compared with their macroscopic counterparts: higher sensitivities in sensors, high efficiencies in reactors, small amount of samples required, fast response, etc. Microelectromechanical systems (MEMS) technologies have been developed by applying semiconductor microfabrication technologies from the late 1980s.
