43203pr@reply-direct.com New and Innovative Chromatography Media


Since 1911 MACHEREY-NAGEL stands for innovation, high quality and reliability in analytical chemistry and life science. MN offers a broad range of products for chromatography, fi ltration, rapid tests, water analysis and bioanalysis as one of today’s leading manufacturers in these fi elds. MN´s expertise in manufacturing of chromatography media is based on many years of experience in silica technology. The development of the spherical HPLC silica NUCLEOSIL®


and the introduction of


commercially available ready-to-use TLC plates and sheets are just two milestones emphasising the pioneering tasks of MN in promoting these separation techniques, which today are omnipresent in analytical labs all over the world.


In September 2017 MN introduced their latest development for solid-phase extraction – CHROMABOND® HLB. This hydrophilic-lipophilic balanced polymeric SPE adsorbent is specially designed for the enrichment


of hydrophilic analytes from polar matrices like water, blood serum or food. With classical C18/C8 modifi ed silica, even with modern hydrophobic polymer adsorbents, retention is often diffi cult. Linked hydrophilic groups of the HLB copolymer interact with polar functional groups of the analytes while the lipophilic backbone interacts with nonpolar hydrocarbon residues to provide enhanced retention. A broad range of columns, cartridges and 96-well plates packed with CHROMABOND®


The latest launches, CHROMABOND® PL for the removal of phospholipids and CHROMABOND®


media. For more information, visit www.mn-net.com/SPE. The hydrophobic HPLC phase NUCLEODUR®


C18


HLB adsorbent can be applied for a wide range of applications (e.g., pesticides from water, pharmaceuticals from serum, antibiotics from honey). Carbon A for analysing acrylamide in drinking water, complement the steadily growing range of innovative SPE


Gravity-SB with its distinct polar selectivity is ideal for method development, because it shows better retention of early eluting compounds. Overall sophisticated


analytical separations, especially for polar compounds (e.g., antibiotics, water-soluble vitamins, organic acids), are recommended applications. The recently introduced biphenyl phase NUCLEODUR® TT2


separation mode of the HPLC phase is based on two retention mechanisms – TT


In order to meet the growing demands on saving analysis time and solvent costs, MACHEREY-NAGEL expanded the portfolio by adding core-shell silica phases with 2.7 and 5 µm particle size. NUCLEOSHELL®


reversed phase and


HILIC columns enable signifi cantly shorter run times at moderate column back pressures and set new effi ciency standards in research and quality control. For more information, visit www.mn-net.com/HPLC.


But can thin-layer chromatography be innovative? For about 50 years MACHEREY-NAGEL has been manufacturing glass plates, as well as aluminium and plastic sheets coated with silica gels and other adsorbents for TLC and HPTLC. Until today, the glass plates SIL G-25 with and without UV indicator as well as the ALUGRAM®


Xtra SIL G aluminium sheets


are very important TLC products which are often used in scientifi c laboratories, but also in clinical, pharmaceutical, natural product and food analyses.


Yes, TLC can be innovative. The application of large volumes of very dilute samples can cause irregular spreading of substance spots, which complicates evaluation. The innovative TLC glass plates SILGUR-25 and the aluminium sheets ALUGRAM®


Xtra SILGUR


– silica-coated plates or sheets with a concentrating zone of inactive kieselguhr – solve this problem by concentrating sample spots on the layer.

Water Purifi cation Units Save Water and Energy


Suez Water UK has responded to increasing laboratory interest in sustainable solutions by introducing ECO options for its popular Select water purifi cation systems. In addition to saving electricity with an intelligent stand-by feature, customers can now save water through high recovery reverse osmosis (RO) systems.


Recovery rates in similar RO-based systems can sometimes be as low as 10%. In other words to produce 5 litres of purifi ed water, up to 50 litres of feed water would be required, with 45 litres being run to drain as waste. By re-engineering the drain fl ow hydraulics and in conjunction with state of the art high recovery membrane technology, Suez Water UK has developed RO systems that can increase recovery rates to around 50%. This small modifi cation can be made retrospectively as part of a service visit.


The intelligent standby option, available on selected models, imposes a sleep mode on the purifi cation unit whenever a set time has elapsed without water being dispensed. During standby, a 10-minute recirculation programme takes place every 2 hours to maintain water quality. The benefi ts of this feature are savings on electricity usage and water wastage.


Further information on these features and their potential savings is available in a Suez white paper: Sustainable Laboratory Water Purifi cation Systems. To calculate the savings made possible by its ECO recovery and intelligent standby options, Suez is inviting labs to submit their own kWh electricity tariff and pence per m3


water tariff, along with the daily operating hours and water usage of their purifi cation units. There is also an offer from Suez to carry out water purifi cation audits on site.


“Laboratories are looking ever more closely at their operations to fi nd new ways of minimising environmental impacts,” said Steve Mines, Sales Director – Water Purifi cation Systems at Suez Water UK. “With our new ECO recovery and intelligent standby options we can help them save water, electricity and money in a very quick and straightforward way.”
