overviewoftheprocessandresultsofinstrument

performancevalidation.

Firstly,theinstrumentperformancevalidationinvolved

severalparameters,includingaccuracy,precision,

linearity,andsensitivity.Toevaluateaccuracy,we

comparedtheinstrumentsmeasurementswithaknown

referencestandard.Forexample,inthecaseofapHmeter,

wetesteditsaccuracybymeasuringthepHofvarious

standardbuffersolutionsandcomparingtheresultswith

theexpectedvalues.

Precision,ontheotherhand,wasassessedbymeasuring

theinstrumentsrepeatabilityandreproducibility.
