Acylation kit
For improved volatility, better thermal stability or low limit of detection in gas chromatography prerequisite: quantitative, rapid and reproducible formation of only on derivative halogen atoms introduced by derivatisation (e.g. trifluoroacetates) allow specific detection (ECD) with the advantage of high sensitivity elution order and fragmentation patterns in MS can be influenced by a specific derivatisation.Reagents for silylation - alkylation (methylation) - acylation are available.Which is the proper reagent for acylation?Test kit for determination of the optimum acylation.
Acylation reagents for GC - Anhydrides
For improved volatility, better thermal stability or low limit of detection in gas chromatography prerequisite: quantitative, rapid and reproducible formation of only on derivative halogen atoms introduced by derivatisation (e.g. trifluoroacetates) allow specific detection (ECD) with the advantage of high sensitivity elution order and fragmentation patterns in MS can be influenced by a specific derivatisation.Reagents for silylation - alkylation (methylation) - acylation are available.Acylation with fluorinated acid anhydrides can be used for alcohols, phenols, carboxylic acids, amines, amino acids and steroids forming volatile, stable derivatives suited for FID as well as for ECD detection.by-products of acylation with anhydrides: corresponding acidsexcess reagent and the acid formed have to be removedHeptafluorobutyric acid anhydride (HFBA)m.w. 410.06, Bp 106 - 107°C (760mm Hg),C3F7 - CO - O - CO - C3F7density d20°/4° = 1.665
Acylation reagents for GC - Bisacylamides
For improved volatility, better thermal stability or low limit of detection in gas chromatography prerequisite: quantitative, rapid and reproducible formation of only on derivative halogen atoms introduced by derivatisation (e.g. trifluoroacetates) allow specific detection (ECD) with the advantage of high sensitivity elution order and fragmentation patterns in MS can be influenced by a specific derivatisation.Reagents for silylation - alkylation (methylation) - acylation are available.Acylation with fluorinated acid amides is recommended for alcohols, primary and secondary amines as well as for thiols under mild, neutral conditions. MBTFA also forms very volatile derivatives with carbohydrates.by-products: corresponding neutral acylamides, which can be easily removed due to their high volatility; because of neutral conditions and favourable chromatographic properties often removal of the bisacylamide is not necessary. Thus sample preparation is much more convenient.MBTFA / MBHFBAN-methyl-bis(trifluoroacetamide) MBTFAm.w. 223.08, Bp 123 - 124°C (760mm Hg), density d20°/4° = 1.55,CF3 - CO - N(CH3) - CO - CF3Due to their purpose, derivatisation reagents are very reactive substances. For this reason they should be stored cool and protected from moisture.The derivatisation reagents are supplied in vials with crimp caps for easy access with a syringe. Vials with pierced sealing disks have limited stability and should be used soon.

Adapter and spindle sets for Viscometers ROTAVISC
DIN S-1: DIN adapter set.O DIN S-1: The open DIN spindle set measures viscosities according to DIN 53019 and can be used with customer-specific vessels. The set includes a single-wall-open-jacket to quickly dive into the sample liquid as well as a coaxial cylinder system for the analysis of the sample at a specific shear rate and shear stress is included.ELVAS-1: The extremely low viscosity adapter spindle set ELVAS-1 includes a double jacket to quickly heat up or cool down the sample as well as a coaxial cylinder system for the analysis of the sample at a specific shear rate and shear stress. This 16 ml spindle is commonly used with the ROTAVISC lo-vi and allows measurements from 1 mPas (water temperature at 20 °C). The spindle without the water jacket can also be used in customer-specific vessels.VAN-1: The vane spindle set allows the viscosity measurement of suspensions. Four vane spindles are included in the delivery.T-SP-Set: Set with 6 T spindlesSAS-1: Spiral adapter to measure the viscosity of very sticky and other viscous samples. Additionally, it is possible to analyse the fluid behavior of different shear rates.SP set-1: Standard spindle set, inculdes 4 spindles (SP1, SP2, SP3, SP4).SP set-2: Standard spindle set, inculdes 6 spindles (SP7, SP8, SP9, SP10, SP 11, SP12)
