Determination of Tetrahydroisohumulones

Instrument Type: HPLC

The Thermo Scientific Tetrahydroisohumulones standard was directly injected onto a Thermo Scientific Hypersil GOLD 3 μm column. With a total run time of 20 minutes, the method allows fast screening for reduced isohumulones in beer. Hence, beers can be screened if they comply with the German purity law.

Determination of Tetrahydroisohumulones using Rapid Separation On-Line SPE

Instrument Type: UHPLC

The BeerNHop solution for high throughput was applied to analyze the Thermo Scientific Tetrahydroisohumulones standard. Automated analyte enrichment was done by on-line solid phase extraction (SPE) on a Thermo Scientific Hypersil GOLD C8 column. Then, the separation was performed on a Thermo Scientific Hypersil GOLD 1.9 µm column with UV detection at 270 nm. With a total run time of 15 minutes, the method allows fast screening for reduced isohumulones in beer. Hence, beers can be screened if they comply with the German purity law.

Determination of Tetrahydroisohumulones using Standard On-Line SPE

Instrument Type: HPLC

The BeerNHop solution using an on-line SPE-UHPLC method was applied for the analysis of the Thermo Scientific tetrahydroisohumulones standard. Automated analyte enrichment was done by solid phase extraction (SPE) on a Thermo Scientific Hypersil GOLD C8 column. Then, the separation was performed on a Thermo Scientific Hypersil GOLD 3 μm column with UV detection at 270 nm. With a total run time of 20 minutes, the method allows fast screening for reduced isohumulones in beer. Hence, beers can be screened if they comply with the German purity law.

Determination of Tetrahydroisohumulones by the BeerNHop Solution with Rapid Separation On-Line SPE

Instrument Type: UHPLC

The BeerNHop solution for high throughput was applied for a direct injection of the Thermo Scientific tetrahydroisohumulones standard. Automated analyte enrichment was done on a Thermo Scientific Hypersil GOLD C8 being used as SPE column. Afterwards, the separation was realized on a Thermo Scientific Hypersil GOLD 1.9 µm column with UV detection at 270 nm. With a total run time of 15 minutes, the method allows easy screening for reduced isohumulones in a beer that is meant to comply with the German purity law.
