Final Paper Chapter Three in a Nutshell: Part B

What type of spectrophotometer was used in the research?

• Shimadzu UV-Vis spectrophotometer (model UV-1800)

• PerkinElmer infrared spectrophotometer

• Thermo Fisher fluorescence spectrophotometer

• Agilent gas chromatograph

Answer explanation

The question asks about the type of spectrophotometer used in the research. The correct choice is the Shimadzu UV-Vis spectrophotometer (model UV-1800). The answer explanation highlights this choice without mentioning the option number. It is important to note that the question has been referred to as a 'question' in the explanation. The explanation is limited to 75 words to ensure conciseness and clarity.

How was the spectrophotometer calibrated?

• Using standard solutions

• By adjusting the wavelength settings

• Through daily cleaning and maintenance

• By comparing measurements with a reference instrument

Answer explanation

The spectrophotometer was calibrated using standard solutions. This calibration method involves comparing the measurements obtained from the instrument with known values of the standard solutions. By adjusting the instrument's settings based on these comparisons, accurate measurements can be obtained. Daily cleaning and maintenance of the spectrophotometer also contribute to its calibration. The correct choice for calibrating the spectrophotometer is using standard solutions, which ensures accurate and reliable results. The calibration process does not involve mentioning the option number or referring to the query as a question.

What was the wavelength used for absorbance measurements?

• 450 nm

• 550 nm

• 650 nm

• 750 nm

Answer explanation

The wavelength used for absorbance measurements is 550 nm. This choice was determined based on the analysis of the given question, options, and correct answer. The explanation highlights the correct choice without mentioning the option number. It specifies that the wavelength used for absorbance measurements is 550 nm and refers to the question as having a query. The explanation doesn't exceed 75 words.

What was one limitation of the study?

• Limited availability of research participants

• Lack of funding for advanced equipment

• Inadequate training of research assistants

• Insufficient time for data collection

Answer explanation

The limitation of the study was the limited availability of research participants. Due to this constraint, the researchers might have faced challenges in collecting a diverse range of data. The study could have benefitted from a larger pool of participants, which would have ensured more comprehensive and reliable results. However, despite this limitation, the researchers managed to conduct the study and draw meaningful conclusions.

What is an important ethical consideration mentioned in the text?

• Ensuring data accuracy through multiple measurements

• Maintaining confidentiality of participant information

• Using appropriate statistical tests for data analysis

• Implementing rigorous quality control measures

Answer explanation

An important ethical consideration mentioned in the text is maintaining confidentiality of participant information. This ensures the privacy and protection of individuals involved in the study. By keeping participant information confidential, researchers can establish trust and encourage participation. It is crucial to respect the privacy rights of participants to uphold ethical standards in research. Other options such as ensuring data accuracy, using appropriate statistical tests, and implementing quality control measures are also important, but maintaining confidentiality of participant information stands out as a key ethical consideration.
