2.1. Objective of Analysis Methods

Okay, so today we are talking about the analysis method just an overview, because each one of these methods will take a long time to completely understand. So, at the level of for environmental analysis, one needs to know 2 things: the objective of doing this is to a selection of method and then it also helped in your preparation of samples.

This portion highlights the two key objectives of analysis methods in environmental sciences. First, these methods assist in selecting the appropriate analytical technique for measuring various environmental parameters. Second, they guide the preparation of samples for analysis, ensuring that the testing process is effective and accurate.

Think of a chef who needs to prepare a dish. The chef must choose the right recipe (the analysis method) and gather the ingredients (samples). If the chef selects a recipe without knowing if they have the necessary ingredients, the dish may not turn out well. Similarly, understanding analysis methods helps scientists choose the right tools to analyze environmental samples.

Because there are a large number of options available and sometimes the selection of method is governed by access to the instrument and also the cost and the logistics of doing it.

This chunk mentions that with numerous analysis methods available, choosing the right one often depends on factors such as accessibility to the required instruments and the overall costs and logistics involved in performing the analysis. If a method is too expensive or if the necessary equipment is not available, it may not be feasible to use that method.

Consider wanting to ride a bike but only having access to a skateboard. While you could look for various biking routes, your choice is significantly limited by what transportation is available to you. Similarly, environmental scientists may find that their analysis options are limited by the tools they can access.

Sometimes it may be very difficult to do some analysis, sometimes you do not have access to it so sometimes prohibitively expensive. Second, it may also help you in sampling methodology.

Here, the speaker emphasizes the need for knowledge about the instruments used in analysis. Scientists do not need to learn every intricate detail but should have enough understanding to ensure they can interpret data correctly and recognize whether the results are reasonable or misleading.

Imagine being a mechanic who needs to troubleshoot a car. You don’t need to know how every single part works, but you should know enough to identify if something is affecting the car's performance. In environmental analysis, knowing about instruments helps researchers interpret the results effectively.

So, the 3 things are important in the standard methods is the analysis of or measurement of the pollutant in matrix using an analytical instrument using a technique.

This section explains that standard methods of analysis are built around measuring pollutants within different environments or 'matrices' using specific analytical instruments and techniques. Understanding these standards ensures that the methods remain consistent and yield reliable data.

Think about a standardized test in school. Everyone takes the test in the same way, ensuring fairness and consistency in how students' knowledge is measured. Similarly, standard methods in environmental analysis provide a consistent framework for measuring pollutants, ensuring reliable results.
