Chapter 20, Problem 20.18P

(a)

Interpretation Introduction

Interpretation:

Purpose of addition of $\text{CsCl}$ while food is digested in Teflon bomb has to be given.

Concept Introduction:

Expression to compute detection limit is as follows:

  $\text{Detection limit} =\frac{3s}{m}$

Formula to compute Lower limit of quantitation is as follows:

  $\text{Lower limit of quantitation}=\frac{10s}{m}$

Here,

$m$ refers to slope.

$s$ denotes standard deviation for sample.

(b)

Interpretation Introduction

Interpretation:

Calibration line has to be drawn and slope and intercept along with standard deviation and $R^2$ has to be determined from spreadsheet.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Metals that interfere and wavelength that should be preferred has to be identified.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Signal detection limit and lower limit of quantitation have to be calculated.

Concept Introduction:

Refer to part (a).

(e)

Interpretation Introduction

Interpretation:

Lower limit of quantitation has to be calculated.

Concept Introduction:

Refer to part (a).
