How Can We Check the Purity of a Substance by using qualitative analysis?

# data[].attributes.body
Whether in manufacturing, cooking or cleaning, substances are most efficient when they're pure. Purity can be defined as the absence of any impurities or types of matter other than the substance itself. You can use numerous tests to check for purity, ranging from simple visual comparison to sophisticated laboratory techniques.

In these laboratories, the amount of the drug is determined in the blood, urine samples, etc., as in doping tests, where players are tested if they have taken prohibited doping.

Analytical Technologies to Improve Human Health

# data[].attributes.body
The selected technologies range from inexpensive point-of-care devices that bring testing to the hands of the patients and/or medical professionals, to more sophisticated analytical tools that provide superb performance for disease diagnosis and characterization in the clinic. Point-of-care technologies share common features such as hand-held usability, disposability, low cost, and ease of operation.

# data[].attributes.body
the analytical technologies highlighted in this virtual issue provide potentially powerful approaches to improve and expedite the diagnosis and treatment of human health conditions. With further development and validation with a larger cohort of clinical samples, these techniques have the potential to translate to the clinic for routine use in patient care.

# data[].attributes.body
Several analytical approaches highlighted are proposed for analysis and diagnosis of clinical samples routinely collected during clinical management of patients, from preoperative assessment of biofluids obtained via minimally invasive clinical procedures to intraoperative tissue evaluation.

There are many colorimetric methods for determining whether a substance is pure or if there are impurities present. These usually involve the use of a chemical for detecting the presence of common impurities, which will turn the chemical a certain color. These methods are simple and are usually designed to determine the presence of impurities, not to determine the amount or the percent purity of the substance. One common use of such colorimetric methods is in forensics, where color tests are frequently used to identify illegal drugs as well as to determine their purity.

Agriculture deals with the production of organic products using both organic and inorganic inputs, thus chemistry forms an integral part of agriculture from the molecular level to the organ level, as it plays a role in agriculture, and developments in this field are due to the active research that has been made in analytical chemistry and from Then its applications to make the land produce abundantly and at the same time to protect it from deterioration and misuse.

Forensic science is a way to use science to help the law and fight crime. It uses the application of scientific methods to help ensure a lack of bias in a legal case, as people’s lives depend on it. There are many types of forensic science, including its subtypes and also many forensic analysis techniques. Television and movies portray very exciting lives for forensic experts; however, the real story is one of extremely careful attention to detail, preserving evidence and being able to communicate well in a court of law. and the qualitative analysis helpful in this situation
