Why do quantitative and qualitative analyses require a different monochromator slit width?

In quantitative analyses, we use wider slit width to let the slit more brightness, to improve the sensitive of detection. In qualitative analysis, we use narrow slit to get higher resolution, avoid other light influence and to detect the specific light wavelength.

What is meant by ammonia gas sensor?
This is a gas measurement technology for improving semiconductor clean room environment, chemical and petrochemical process analyses. A typical ammonia detection system is for cold storage or food processing plants.
Chemical analysis of compost?
The chemical analysis of compost includes stability tests; and analyses of solid/waste chemical nutrients and of heavy metals and pesticides. Soil and waste nutrient analyses tell pH, and soluble salts levels. The pH typically may be about 7.0. Soluble salts level may be high if compost materials included animal manure. A relatively high reading is 4.0 mmhos/cm, on a solution of two parts water to one part compost. Such a reading may recommend leaching/rinsing, down to a conductivity measure of 2.0 mmhos. Compost exceeding this last reading may damage ornamentals. They also give percentages of all elements. Elements include calcium, magnesium, nitrogen, phosphorus, or potassium. There are threshold values to be met in terms of metals. Such metals include cadmium, chromium, copper, lead, mercury, nickel, polychlorinated biphenyls, and zinc.
The solid acid is dissolved in 100 mL of deionized water followed by 10 mL ethanol How does this added volume affect?
The added ethanol will not affect the pH whatsoever, due to the fact that ethanol cannot donate hydrogen ions or accept them. The added volume will, however, not affect the molar mass of the acid that you will report from the analyses. You use the volume of base that is used to titrate the acid to find the moles of acid and base at stoichiometric point so the added volume will not affect the molar mass.
Compounds that are made from oil are called?
I will answer this by first defining oil as the natural petroleum liquids as extracted from reservoirs. In terms of distinct chemical compounds, there are hundreds of identified compounds that may be contained in petroleum. Generally, they are broken into two groups, the organics and inorganic compounds. Organic compounds include alkanes, cycloalkanes and aromatic hydrocarbons. Inorganic compounds include nitrogen, oxygen, sulfur and trace amount of metals nickel, copper, iron, vanadium. A typical compositional analyses of petroleum will provide the content of each of the alkane components up to about C7 (including the isomers) and lump the remaining compounds as C7+ and the detectable H2S, O2 and N2.

What is the researchers role in conducting qualitative research and how is this different from quantitative research?
In qualitative research, the researcher's role is to gather in-depth data through interviews, observations, and analysis to understand the underlying meanings and experiences of participants. This approach allows for greater flexibility, exploration, and understanding of complex social phenomena compared to quantitative research, which focuses on numerical data and statistical analyses to make generalizable conclusions. Quantitative research aims to measure relationships between variables and test hypotheses using structured data collection methods.
Researchers generally use surveys secondary analyses of existing statistical data and experimental designs?
