Which parameter is important when selecting analytical methods?

When selecting analytical methods, cost is a vital consideration because it directly impacts the feasibility of the analysis within the budget constraints of a laboratory or organization. If a method is too expensive, it may not be practical for regular use, regardless of its other advantages, such as precision or accuracy. Therefore, evaluating the costs associated with reagents, maintenance, and instrumentations is essential to ensure that the analytical method can be implemented routinely without exceeding financial limits.

While other factors like precision, analysis time, and equipment type are important, they often become secondary if the method is cost-prohibitive. Budget constraints may dictate which methods are actually feasible for a specific application, making cost a critical parameter in the selection process.
