Nové limity pro testování pitné vody

Ačkoliv moderní zemědělství potřebuje vycházet z přesných dat o půdních, rostlinných i environmentálních podmínkách v reálném čase, cenově dostupná, dostatečně citlivá a zároveň robustní monitorovací zařízení pro tento účel v současné době chybí. Jako vhodné řešení se podle vědců nabízí nízkonákladové senzory založené na nových chytrých materiálech a technologiích tisku. Dosavadní výsledky multiioborového výzkumu i návrhy na vývoj těchto zařízení představili výzkumníci z Česka, Velké Británie, Španělska i USA v přehledovém článku v prestižním časopise <a target="_blank" rel="noopener noreferrer" href="https://www.nature.com/articles/s41467-026-68778-6#Abs1">Nature Communications</a>.„Senzorické technologie pro monitorování zdraví rostlin jsou stále v plenkách. Na trhu jsou běžné dostupné jen jednoduché senzory, které jsou schopné monitorovat pouze základní parametry jako například pH, vlhkost v půdě, případně teplotu. Pokud však mají zemědělci čelit současným výzvám včetně klimatických změn a zajistit pro lidstvo dostatek potravy, potřebují mnohem účinnější pomocníky, jež jim umožní monitorovat například i různé patogeny včetně bakterií či plísní. Podle nás je vhodným řešením kombinace nových chytrých materiálů a tisku pro produkci levných, odolných a škálovatelných materiálů,“ uvedl první autor článku David Panáček z CATRIN, který na studii pracoval během své stáže v Imperial College London.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg" alt="CATRIN: David Panáček" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg 208w," sizes="100vw" width="1536" height="1152">Senzory pro monitorování zdraví rostlin například v porovnání s podobnými zařízeními pro humánní medicínu pokulhávají. Klíčovou roli v možném posunu hraje podle autorů pokrok v materiálových vědách, jenž vývoj škálovatelných senzorových technologií umožní. „Tiskové techniky včetně inkoustového tisku, sítotisku, aerosolového tisku, 3D tisku a přímého laserového zápisu nabízejí flexibilní cesty k výrobě ohebných senzorů, senzorů pro velké plochy i senzorů integrovaných přímo do rostlin. Přehledový článek shrnuje nedávný pokrok v oblasti tisknutelných nízkorozměrných materiálů pro zemědělské senzory, analyzuje jejich fyzikálně-chemické vlastnosti ve vztahu k senzorovému výkonu a diskutuje hlavní výzvy a budoucí příležitosti vyžadující mezioborovou integraci,“ uvedl jeden z korespondujících autorů Michal Otyepka.Výzkum propojil materiálové vědce, chemiky, biology, odborníky na senzing i technologie tisku. Materiálový výzkum a využití chytrých materiálů na bázi grafenu zaštítili vědci CATRIN Univerzity Palackého a VŠB-Technické univerzity Ostrava, znalostmi o vývoji rostlin, jejich reakcích na stresové podmínky i monitorování jejich vlastností přispěli rostlinní biologové z CATRIN, o oblast elektroniky se postarali výzkumníci z Imperial College London, technologiím tisku se věnovali zástupci <a target="_blank" rel="noopener noreferrer" href="https://lcms.cz/companies/36">CEITEC – VUT</a>. V týmu nechyběli ani přední odborníci na senzing z Katalánského institutu nanověd a nanotechnologií v Barceloně a svými bohatými znalostmi přispěl i „otec senzingu a elektrochemie“ Joseph Wang z University of California San Diego.„Jedná se o průlomovou studii na toto téma, k níž se podařilo přizvat skutečně velká jména v daných oborech. V neposlední řadě studie dokládá to, že interdisciplinarita v CATRIN dává vzniknout zcela novým a perspektivním výzkumným tématům, jako je rostlinný senzing a jeho využití pro studium interakce rostlin s prostředím a chytrém zemědělství,“ doplnila další z korespondenčních autorů Nuria De Diego. &nbsp;

Recent advances in liquid chromatography hardware and UHPLC columns have enabled LC and LC/MS experiments to be faster and more sensitive.
However, running HPLC experiments on low-dispersion instruments can lead to earlier retention times, elution order changes, and differences in resolution compared to that previously observed. Additionally, methods developed on HPLCs and UHPLCs from different vendors can also result in differing chromatographic profiles.
Join us to learn how to best utilize Agilent Intelligent System Emulation Technology (ISET) to get similar retention times and resolution to previous runs while future-proofing your laboratory with high-end UHPLC instrumentation.

What's Wrong With My Chromatography? Is it the Column, Method or Instrument

Develop your troubleshooting skills. Common chromatography problems.

What's Wrong With My Chromatography?

A rugged HPLC method is one that produces reproducible analytical results under actual use conditions.
To produce results that are accurate, repeatable, and reproducible an HPLC separation must either be relatively insensitive to small variations in analysis conditions, or those variations must be identified and controlled satisfactorily. This is termed method robustness. It is a required validation criterion for analytical methods submitted to national and international regulatory agencies.
In this presentation we will discuss:
<ul>
<li>Important factors that affect the robustness and ruggedness of HPLC separations
</li>
<li>Describe the importance of and the advantages of considering these factors as part of the method development process
</li>
<li>The development of a robust method is not only cost effective in the long term, but it also increases the likelihood of successful method transfer to other in-house or contract analytical laboratories.

Agilent Technologies: Gradient, Reversed Phase HPLC - The Why, What, When and How

Gradient, Reversed Phase HPLC - The Why, What, When and How

Developing reliable gradient methods is more challenging compared to isocratic methods.

Data quality and data integrity are critical in key decisions supporting the safety and efficacy of pharmaceutical products. Regulatory observations in pharmaceutical laboratories routinely cite concerns regarding the suitability of analytical methods, particularly chromatographic methods that require analysts to intervene, adjust or repeat testing.
Inspired by a suite of new ICH guidelines, chromatographers are now managing methods using a lifecycle approach to improve the consistency, ruggedness and quality of separations to enable right-first-time analyses. Development and deployment of these analytical methods to modern, routine-use HPLC platforms mitigates the risk of invalidated data, continually adjusted or manual peak integration, and system suitability failures.
The webinar hosts will examine key challenges faced in the routine analysis laboratory and demonstrate method transfer to the new Waters Arc HPLC System. The Arc HPLC is designed to receive transferred methods seamlessly and run existing HPLC methods with improved robustness and precision over traditional HPLCs, avoiding system suitability failures and the invalidation of results. The Arc family of LC systems, when paired with appropriate column technology and gold standard, compliant-ready Empower Software, combine to offer robust performance in routine analysis, facilitating data review, eliminating burdensome quality or compliance documentation, and improving the overall quality of laboratory data.
<h3>Key learning objectives</h3>
<ul>
<li>Current trends in regulatory observations referencing chromatography analyses</li>
<li>How analytical method performance can be a root cause of data integrity concerns</li>
<li>How new ICH guidelines will influence how chromatographic methods are developed and documented, resulting in more stringent system suitability and reproducibility requirements</li>
<li>How improvements in the performance and ruggedness of HPLC instruments can improve data quality</li>
</ul>
<h3>Who should attend</h3>
