Online or Offline Sample Preparation

24 Nov 2014

Sample preparation in an automated analytical process can be managed either by online or offline workstations. There are advantages and disadvantages to both approaches: this white paper examines the factors which have a bearing on the suitability of each approach, and concludes that there is no univocal answer to this dilemma; instead multiple factors and variables should be examined to find the best approach for your own lab.

HT4000L HPLC Autosampler

HTA s.r.l.

HT4000L is an HPLC autosampler for high presise injection into HPLC, UHPLC, LC/MS and IC systems. HT4000L is lab automation ready. In fact HT4000L besides working as a standard HPLC autosampler, can take care of many sample preparation tasks as no standard autosampler has been able to assist up to now. Basic sample preparation capabilities includes dilution, precolumn derivatization, pH spiking and internal standard addition in place or in an empty vial by sample dispatching.If standard sample preparation capabilities are not enough, by using HTAPREP - lab automation software – complex and custom autosampler methods can be supported. HT4000L offers endless possibilities: any sample preparation procedure or complex sample introduction become available.Key features: Easy to use Large sample capacity Application versatility Modular and scalable Lab automation ready

HT4000A Sample Prep Workstation

HTA s.r.l.

HT4000A is a sample preparation workstation that allows automation of sample preparation procedures by taking care of a large number of operations such as liquid handling, purification or filtration (including Solid Phase Extraction (SPE), Micro Extraction by Packed Sorbent (MEPS), Whatman® Mini-UniPrep® syringeless vials, syringe-filters and liquid/liquid extraction (LLE)), tracking and further sample processing such as vortex, automatic uncap/recap, and weigh. The modular design allows easy configuration and affordable costs. The liquid handling module is included in each configuration, while all other modules are included, according to your requirements. You get your HT4000A instrument tailored and designed to fit it to your lab workflow: furthermore, by adding or removing modules, you are quickly able to deploy an additional or different sample prep procedure. HT4000A is supplied with HTAPREP – lab automation software – that offers powerful method development by a simple drag & drop approach and smart sample processing: complex routine and experiments can be defined in a few easy steps. Key features: Flexibille and customizable Cost effective Modular and scalable Easy programmable
