Chapter 33, Problem 33.6QAP
Interpretation Introduction
Interpretation:
PerkinElmer Inc. makes the lab-on-a-chip technology which is used in several analyzers. The detail of the use of microfluids in one PerkinElmer analyzeris to be described by using the search engine. The types of the possible determination, advantages and limitation of the lab-on-a-chip technology for an analyzer are to be described.
Concept introduction:
The lab-on-a-chip technology is a technology in which several laboratory functions are integrated on the single integrated circuit or on chip. This integrated chip is about few square centimeter or millimeters to acquire high throughput screening and automation.
