What Are Sugar Alcohols?
Sugar alcohols (polyols) are reduced monosaccharides that contain multiple hydroxyl groups, making them highly polar and often isomeric. Common representatives such as erythritol, xylitol, sorbitol, mannitol, and inositols are widely used in biochemical research, fermentation systems, and formulation development.
Due to their similar structures and low molecular weights, sugar alcohols are notoriously difficult to separate and quantify using standard methods. Their high hydrophilicity leads to poor retention in reversed-phase LC, and isomeric forms often co-elute or share identical mass transitions. Reliable analysis requires platform-specific separation strategies, tailored ionization conditions, and validated calibration schemes.
Creative Proteomics applies optimized HILIC–MS/MS and derivatized GC–MS/MS workflows to resolve these challenges, enabling accurate, isomer-specific quantification across diverse sample types.

FAQ of Sugar Alcohols Analysis Service
What challenges commonly occur in sugar alcohol quantification?
Isomeric overlap, low ionization efficiency, and matrix interferences are frequent issues. Accurate quantification requires method-specific separation strategies, stable isotope standards, and recovery-validated workflows.
Can sugar alcohol isomers like sorbitol and mannitol be reliably separated?
Yes. When using HILIC–MS/MS with optimized gradient and column selection, baseline resolution (Rs >1.5) can be achieved, allowing precise quantification of structurally similar sugar alcohols.
How do you ensure data reliability across complex sample types?
Each run includes matrix-matched calibrators, internal standards, bracketing QCs, and orthogonal verification (e.g., GC–MS or PAD) to confirm specificity and recoveries across sample classes.
What matrices are compatible with sugar alcohol analysis workflows?
Validated matrices include fermentation broth, food extracts, formulation excipients, cell culture media, and aqueous buffer systems free of interfering polyols (e.g., glycerol or propylene glycol).
Can your methods distinguish between cyclitol isomers such as myo- and scyllo-inositol?
Yes. We employ LC–MS/MS with optimized retention and transition ratios to differentiate inositol stereoisomers, ensuring accurate isomer-specific profiling in biological and industrial samples.
What internal standards are recommended for quantitative accuracy?
Stable isotope-labeled analogs (e.g., sorbitol-13C6, erythritol-d4) are used where available to correct for extraction efficiency and instrument variability, particularly in low-abundance applications.
How do you confirm the identity of each sugar alcohol detected?
Confirmation is based on multiple criteria: retention time match, ion ratio agreement within ±20%, and, when required, cross-platform validation using GC–MS or HPAEC–PAD.
Why do polyol analyses often fail in standard LC–MS labs?
Most labs lack the necessary chromatographic resolution for isomer separation or the ion source optimization required for polyol detection, leading to inaccurate results or false negatives.
Can you accommodate high-throughput screening for sugar alcohols?
Yes. Our platform supports scalable batch analysis with consistent retention reproducibility (RT RSD ≤1%) and automated data processing for large sample sets.
What detection limits can be expected for sugar alcohol analysis?
LOQs vary by compound and matrix, but validated methods typically achieve ng/mL-level sensitivity using scheduled MRM or SIM for derivatized analytes.
