Advanced Analytical Chemistry: Lecture 1

Overview
We’re going to begin a new series today. This covers some analytical chemistry, which deals with instrumentation. Our first lecture costs 29 minutes. The audience appears to be graduate students.

Details
Two immiscible liquids. Perhaps hexane and water. Put in some compounds we’d like to seperate. Put them in at low concentration for a linear chromotography. Benzene would stay with the hexane.

A seperatory funnel can only seperate two phases. Can’t get 100% purity. To do a perfect amount of seperation, you need infinity entropy.

Resonance or entropy is usually the answer whenever something really bothers you.

We think of the number of plates in a chromatography column. It’s a continious process that we think of discontiniously.

Partition factor = K =
K = products/reactants

Moles = concentration x volume

Phase ratio = Xa organic/ Xa polar

Retention factor = Xa/X total

RF tells you where something is because it shows the fraction in either phase.

The solute in the stationary phase is a reactant, in the mobile phase is a reactant.

mobile phase
stationary phase

Review:
Resolution = seperation
CH2=CHCH2SCH3 AMS allyl methyl sulfide

Ag has the highest electrical and thermal conductivity, Ag+
C6H12O6 = 2C2H5OH + 2CO2 + 2ATP
The stronger the interactions between the polar analyte and the polar stationary phase (relative to the mobile phase) the longer the elution time.
Each eye has six muscles that control its movements: the lateral rectus, the medial rectus, the inferior rectus, the superior rectus, the inferior oblique, and the superior oblique.
4 classes of blood loss
Class I -15% blood volume
Class 2 15-30 tachycardia, pallor
Class 3 30-40
CLass 4 40+ resusictation
Octasulfur is S8 in a puckered ring.

BLISS – blend in, low, irregular, small, secluded
METT-TC: mission enemy troops terrain time civilians
SALUTE size activity location unit time equipment
Sternum: manubrium, body, xyphoid process (suprasternal/jugular notch)
Stomach: fundis, body, pylori
Small intestine: duodnum, jujunum, ileum
pi donor ligands/weak field ligands/high spin

Ambush: category – hasty/deliberate, type – point/area, formation- linear/L shaped.
LACE liquid ammunition casualties equipment
Ag has the highest electrical and thermal conductivity, Ag+
C6H12O6 = 2C2H5OH + 2CO2 + 2ATP
Maltose is two glucoses.
Sucrose is glucose and fructose.
Lactose is glucose and galactose.
Fire: O2, fuel, heat, chain reaction
Stomach: fundis, body, pylori
Prisoner Handling: search silence segregate speed safeguard tag
N2 + 3 H2 ⇌ 2 NH3 + 92kJ
Redfield Ratio C:N:P 106:16:1
Air = N2, O2, Ar, CO2, Ne
AFR air fuel ratio
Air: Fuel 14.7:1
14.7 lean
The lower the excess air, the richer the flame.
n-pentane, isopentane, neopentane
C4H9Li + H2O → C4H10 + LiOH
cetane being an old name for hexadecane
alkane – alcohol-aldehyde-COOH
The higher the excess air, the leaner the flame
