The document summarizes an experiment assessing system suitability parameters for an HPLC method using acetone, benzene, and toluene as analytes. The method evaluated resolution, tailing factor, and theoretical plates at different mobile phase compositions of water and acetonitrile. The results showed that resolution and theoretical plates decreased while tailing increased when the mobile phase composition was changed from 50:50 to 60:40 water:acetonitrile. Chromatograms are also presented to visualize the separation achieved with each mobile phase.

3. INTRODUCTION
• HPLC stands for high performance liquid chromatography or
high pressure liquid chromatography.
• It is a form of liquid chromatography used to separate
compounds that are dissolved in solution.
• HPLC instruments consists of a solvent reservoir, pump, an
injector, a column, a detector and a data collection device.
• Used in biochemistry to identify, quantify and purify the
individual components of a mixture.
• Our project is based on reversed phase chromatography:
stationary phase is non-polar (hydrophobic) and mobile
phase is polar (hydrophilic). Main principle of separation is
adsorption based on polarity.

4. SYSTEM SUITABILITY
• System suitability are used to verify that the resolution and
reproducibility of the chromatographic system are adequate for the
analysis to be done.
• Some parameters which can be checked using the System
Suitability Testing are:
1. Resolution (R) =
𝟐.𝟎(𝑹𝒕 𝟐−𝑹𝒕 𝟏)
(𝑾 𝟐+𝑾 𝟏)
where, 𝑅𝑡2=Retention time for peak 2
𝑅𝑡1 = Retention time for peak 1
(𝑤1+𝑤2)= sum of peak widths at
baseline between tangent lines.
2. Plate count (N)= 𝟏𝟔(
𝒕
𝒘
) 𝟐
where, t=Retention time
w=Width of the peak at baseline

5. .
3. Retention time: It is important that retention time be fairly constant
because the data system uses retention time to identify peaks.
4. Pressure: The suitability testing must be carried out within set pressure
limits.
5. Tailing factor (T) =
𝑾 𝟎.𝟎𝟓
𝟐𝒇
where, 𝑤0.05 = width of the peak at 0.05h
f = width between left tangent
and the line of maximum peak.

6. • Aim: To perform system suitability check for HPLC column
(Zorbax XDB- 150mm x 4.6mm x 5µm).
• Objective: To assess the changes in USP Resolution, USP Tailing
& theoretical plate of HPLC column (Zorbax XDB- 150mm x
4.6mm x 5µm) by using a mixture (Acetone, Benzene, Toluene)
upon changing the composition of mobile phase.

17. • As per polarity table given below the polarity of the used compounds are
as Acetone > Benzene > Toluene.
• Naturally in Reverse phase chromatography, acetone will be eluted first
followed by benzene and toluene, which in evident in the
chromatograms.
• Upon decreasing the polarity of the mobile phase (adding extra
acetonitrile to the mobile phase) the runtime of the experiment was
reduced.
• We assessed that even after reducing the polarity the separation was good
but decreased by quite an amount, but it hardly affected the USP tailing.
DISCUSSION
Solvent Relative polarity Eluent strength
Toluene 0.099 0.24
Benzene 0.111 0.32
Acetone 0.355 0.56

18. • Separation of the compounds (acetone, benzene, toluene) in a
mixture was not hampered by change in composition of mobile
phase.
• The peak shape and orientation were not hampered upon change
of mobile phase.
• The resolution between the chromatogram was also very good.
• It can be concluded that the mixture of acetone, benzene &
toluene, could be successfully employed as system suitability
check solution.
CONCLUSION
