Food and Beverage Testing

Food and beverage testing laboratories face challenges in extracting and cleaning up trace analytes from complex matrices like oils, beverages, and processed foods. Microlab supplies mixed-mode and organic copolymer SPE columns designed for multiresidual pesticide analysis, drug

Context

The Problem In This Sector

Pain Points

  • Low recovery of pesticides due to strong matrix interference from fats, pigments, or sugars
  • Inconsistent cleanup leading to co-elution and false positives in GC/MS or LC/MS
  • Breakthrough of analytes during loading due to insufficient sorbent capacity or poor bed stability
  • Method failure when switching between different SPE sorbents without revalidation
  • High variability in column-to-column performance affecting reproducibility across batches

What This Sector Needs

  • SPE columns with proven recovery and low variability across multiple runs
  • Mixed-mode sorbents that combine multiple retention mechanisms for complex sample cleanup
  • Columns with ultrathin frits to ensure uniform flow and prevent clogging
  • Consistent part numbering and packaging to ensure batch-to-batch traceability
  • A single supplier for multiple SPE column types covering both pesticide and drug analysis
Where It Is Used

Typical Application Scenarios

  • Multiresidual pesticide analysis in fruits, vegetables, and wine using GCB/NH2 and GCB/PSA columns
  • Cleanup of drug metabolites in biological fluids for food safety testing using C8/SAX and C8/SCX columns
  • Extraction of polar and non-polar compounds from dairy and beverage matrices using HLB and MAX columns
  • Matrix interference removal in processed food samples with high fat or sugar content
  • Method development and validation using SPE columns with defined particle size, pore size, and surface area
Process

How We Work With You

Specify

Select the column type based on analyte polarity and matrix interference, matching sorbent chemistry to the target compound class

Sample

Trial quantities of the candidate column are supplied to validate recovery and cleanup efficiency before bulk purchase

Standardise

Part numbers are assigned to each column size and chemistry, ensuring consistent reordering and method traceability

Supply

Repeat supply of the same specification, with OEM packing available for private-label distribution

FAQ

Frequently Asked Questions

Which SPE column should we use for multiresidual pesticide analysis in fruit?

Use GCB/PSA or GCB/NH2 columns for effective removal of pigments, sterols, and fatty acids in fruit samples

Can we use C8/SAX for basic drug metabolites in food matrices?

C8/SAX is designed for acidic compounds in biological fluids. For basic drugs, use C8/SCX or MCX columns

Do your HLB columns have a wide pH range?

Yes, HLB columns are stable from pH 1 to 14 and compatible with most common solvents

Will changing to your SPE columns require method requalification?

That is your decision under your own quality system. The column dimensions and sorbent chemistry are specified to match common industry standards

Do you supply under our own label?

Yes. The OEM division covers OEM plastic devices, OEM contract manufacturing, and membrane die-cut and packing
