(a)
Interpretation:
Difference between the instruments used for supercritical chromatography (SFC) and high-performance liquid chromatography (HPLC) needs to be explained.
Concept introduction:
In Chromatographic, a solution separation technique, there is use of stationary phase and mobile phase. If the mobile phase used is a supercritical fluid, then technique employed is termed as supercritical fluid chromatography.
(b)
Interpretation:
Difference between the instruments used for supercritical chromatography (SFC) and gas chromatography (GC) needs to be determined.
Concept introduction:
Supercritical fluid chromatography is form of separation techniques that uses carbon dioxide as mobile phase.
Gas chromatography is another specific means of separating substances from its mixture that contains volatile compounds that have gas phase.

- What types of samples can be analyzed by IR?How are substances that are opaque (nottransparent) handled using this technique?arrow_forwardMany ions form colored solutions when dissolved in water. For example, aqueous Cu2+ solutions are light blue and aqueous Ni2+ solutions look light green. These metals in particularare often found in stainless steel. Would you expect their presence in your samples to interfere in the spectrophotometric analysis of permanganate at 525 nm? Why or why not? I think the answer is that I would expect the Cu2+ in my samples to interfere but not Ni2+ because the Ni2+ is green, signifying a higher wave length that the spectrometer wouldn't be able to pick up on because it was only set to 525 (blue-ish) where as the green is 530-ish.
