About Me

From the Pharmaceutical Laboratory to Practical Tools

I'm Mirela Gorjanu, MSc, a pharmaceutical analytical scientist with more than 20 years in HPLC, LC-MS, method development, method validation and troubleshooting.

Knowing the science is only half the job. Knowing what to do when the experiment doesn't behave is the other half. Every guide, template and app here is built for that second half: the tailing peak, the lost resolution, the validation result that doesn't make sense, the method that fails after transfer.

Built for analysts in pharmaceutical R&D, QC, validation, stability, CROs and academia. Acceptance criteria are anchored to ICH Q2(R2), ICH M10 and USP.

PRACTICAL PHARMA SCIENCE

Practical Pharma Science

PRACTICAL PHARMA SCIENCEâ„¢

Practical AI Tools & Training for Analytical Scientists

Develop better methods. Design smarter experiments. Validate with confidence. Troubleshoot faster. Transfer methods more reliably.

Practical Pharma Scienceâ„¢ brings together practical analytical-science software, visual training resources, practical guides, troubleshooting systems and laboratory-focused workflows created for scientists working with HPLC, LCMS, GCMS, method development, validation, DoE and pharmaceutical analysis.


BUILT FOR THE REAL LAB

Not another collection of generic AI tools.

These resources are designed around the questions analytical scientists actually face:

What should I try next?

Why is my method failing?

How should I design the experiment?

Is my validation strategy adequate?

What could be causing this degradation?

How can I transfer this method successfully?

Experimental Design

Use structured experiments to understand critical factors.

Method Validation

Organise validation thinking and documentation.

Degradation Studies

Plan and evaluate forced-degradation investigations.

Method Transfer

Understand system differences and transfer conditions systematically.

WHY PRACTICAL PHARMA SCIENCEâ„¢?

REAL-WORLD EXPERIENCE

Created by Mirela Gorjanu, MSc, a pharmaceutical analytical scientist with more than 20 years of industry experience.


PRACTICAL FIRST

The goal is not to make analytical science more complicated.

The goal is to make it easier to understand, apply and teach.


VISUAL LEARNING

Complex concepts are transformed into structured workflows, diagrams, posters, practical examples and decision-based learning resources.


SCIENCE + TECHNOLOGY

Practical Pharma Scienceâ„¢ combines pharmaceutical analytical chemistry with modern AI-assisted tools and digital learning.





FROM THE LAB TO THE DIGITAL WORKFLOW

My background started with analytical chemistry and pharmaceutical laboratories.

I spent years working with chromatography, method development, validation, troubleshooting and analytical problem-solving.

Then I started learning something completely new:

coding.

Today, I am combining those two worlds to build practical digital tools for analytical scientists.

Practical Pharma Scienceâ„¢ is the result.
