Client Needs: A client required a specific impurity method for their new, strongly basic drug candidate.
Challenges: The compound exhibited severe peak tailing and co-elution with two critical process impurities under standard conditions.
Solution: Our team executed a systematic screening of specialized columns designed for basic compounds. Employing a low-pH phosphate buffer system suppressed silanol effects and dramatically improved peak shape. Through meticulous optimization of the gradient profile, buffer concentration, and column temperature, we achieved baseline separation of all specified impurities with high sensitivity.
Outcome: We delivered a robust, high-performance method with excellent peak symmetry and resolution.
Client Needs: A client needed to monitor the optical purity of a challenging pair of chiral synthetic intermediates.
Challenges: The structurally similar isomers showed no separation on multiple conventional chiral columns, and the sample had limited stability.
Solution: We initiated a multi-dimensional chiral screening strategy, testing specialized phases based on cyclodextrin and macrocyclic antibiotic chemistries. Under polar organic mode, precise low-temperature conditions were applied to achieve optimal separation. The sample solvent was concurrently optimized to ensure analytical stability throughout the run.
Outcome: Baseline separation of the enantiomers was achieved, providing a critical tool for process control.
Client Needs: A client needed to accurately quantify encapsulated ethanol levels in their liposomal product.
Challenges: The phospholipid matrix severely suppressed the headspace volatilization of ethanol, leading to poor and variable recovery.
Solution: We employed a matrix-matched standard approach and systematically optimized headspace parameters. The introduction of a stable isotope-labeled internal standard effectively compensated for variability in sample preparation and injection. Method validation included an assessment of interference from different batch matrices.
Outcome: A highly accurate and reproducible method was established, reliably determining the true ethanol content.
Challenging Sample Analytical Method Development involves creating and optimizing analytical methods for complex samples with unique properties. These samples may include unstable compounds, difficult-to-separate components, chiral substances, or complex matrices. We use customized experimental designs, optimized separation techniques, and advanced detection platforms to ensure accurate and efficient analysis, even for the most challenging samples.
For unstable compounds, we implement strategies like antioxidant protection, low-temperature storage, and degradation prevention techniques. By optimizing solvent systems, chromatographic conditions, and sample handling protocols, we minimize sample degradation during the analysis process. Our goal is to preserve the sample's integrity and provide accurate, reliable results under challenging conditions.
Chiral separation is a common challenge in analytical methods. We address this by selecting and optimizing specialized chiral columns, adjusting solvent systems and pH conditions to efficiently separate chiral isomers. For different chiral compounds, we customize chromatographic conditions to ensure high separation efficiency, recovery rates, and accuracy, tailored to the specific needs of the sample.
For complex matrix samples (such as food, environmental, or plant extracts), we consider the matrix effect, which can cause interference. We optimize sample preparation techniques such as solid-phase extraction (SPE) or solvent extraction to remove matrix interference and adjust chromatographic and detection conditions to enhance sensitivity and accuracy. This ensures reliable results and minimizes false positives or negatives due to matrix effects.
For high-viscosity or complex samples, we develop customized analytical methods, including optimized chromatographic columns and tailored sample preparation procedures. We adjust the mobile phase, column temperature, and separation mode to ensure efficient separation and analysis of target components in complex matrices. This approach enhances separation efficiency and ensures accurate analysis while maintaining high throughput and reproducibility.
