Earthquake disaster in Japan – Are there changes for me?

The flow of harrowing news concerning the effects of the strongest earthquake yet and the resulting tsunami on the north-eastern coast of Japan doesn’t stop. The final extent of this devastating event is not yet known.

Our condolences are sent to those who have lost their families, friends, homes and belongings or are only indirectly affected by the massive consequences of this catastrophe. We are following the news with deep concern.

After receiving the first information from Japan on Friday 11th of March, YMC Europe immediately contacted the parent company in Kyoto and we got confirmation that no employees of YMC Co., Ltd. and none of their relatives have been hurt and also that the production facilities in Komatsu are able to continue operation without any interference as regards to the great distance inbetween.

After several discussions between Mr. A. Schanze (Managing Director, YMC Europe GmbH) and Mr. A. Miura (President, YMC Co., Ltd.) it was also confirmed that currently there is no interference with the manufacturing processes at the production sites in Komatsu. Therefore we can be assured of an ongoing reliable and prompt supply of YMC products.

Furthermore the exports of deliveries from YMC Co., Ltd. are now done from the airport in Osaka, which is near the Kyoto area and therefore also not affected of neither the earthquake nor the tsunami. This also guarantees the security of supply to European and US customers.

Mr. Ujma (ujma@ymc.de) is available at your convenience to answer your questions regarding this target situation and its implications for YMC.

YMC capillary columns

With the introduction of YMC capillary columns, YMC phases are also now nano-LC/MS compatible. With small column IDs, YMC capillary columns are suitable for extremely small sample volumes and very low fl ow rates. Even sample with low concentrations can be analyzed effectively.

Capillary columns are now available in the following dimensions:

µm ID 50 mm length 75 mm length 100 mm length 150 mm length
75 590,- € 590,- € 590,- € 590,- €
100 590,- € 590,- € 590,- € 590,- €
300 590,- € 590,- € 590,- € 590,- €
500 590,- € 590,- € 590,- € 590,- €

YMC-Kapillarsäule

We recommend the use of pre-columns for highly contaminated samples:

YMC Vorsäule
µm ID 5 mm length
300 490,- € (package of 5)
500 490,- € (package of 5)


The pre-columns connect to the capillary column with a pre-column coupler which is included.

YMC Vorsäule und Kapillarsäule

Pre-columns can also be used as a trapping column!

YMC capillary columns are available with all YMC phases with a pressure rating of 250 bar for 20 and 30 nm porosity phases and 300 bar for 6, 8, and 12 nm porosity phases.

The delivery time for all columns is 1 week.

The YMC HG-series: High Quality low price silica material

Is it possible to get the best of both worlds? Better quality at better price?

It is possible with the new YMC HG-grade series of silica based materials! These new phases combine the trusted selectivity of the YMC*gel materials with a new high performance silica base. The most obvious advantage of the new silica base is its extended mechanical stability which is due to an improved production process for the base silica. Traditionally, many silica particle formation processes suffer from imperfections, such as empty particles (so called balloon particles) or simply damaged particles. Each of these imperfections increases the risk of the formation of fines. YMC’s new production process produces perfectly smooth, spherical particles without these “balloon particles” (see scanning electron microscopy (SEM) images below). More importantly, however, particles produced with the new process also show narrow pore size and superior particle size distribution immediately after formation and therefore require less classification. Not only does this reduce the risk of subsequent particle damage, it also means that less energy is required for classification of the material. This results in the material having better performance with lower production costs.

This advantage of lower production costs is passed to you: the customer.

YMC HG-Series of silica based materials

Trusted selectivity - always available:

Customers trust YMC to produce the same selectivity day after day, year after year. We certainly continue to deliver precisely this! Indeed we also continue to give our long term availability assurance: All those materials you currently use will continue to be available. We assure you that YMC will supply the materials currently in use in a validated production procedure or validated method with the same specifications and quality, for as long as the process / the method is running.

At the same time, the new HG-series materials will provide yet another option to lower costs and improve the efficiency of the preparative HPLC process. They are produced with the same selectivities as YMC*Gel. This means right from the start, there is the full range of C18/C8/C4/Phenyl and all other materials available in HG quality.

The result:
New silica base + conventional bonding = same reliability + lower costs.

Preheating of mobile phases - "nice-to-have" or "need-to-have"?

Controlling the temperature of a column is a prerequisite for reproducible results in HPLC. Column ovens are part of most HPLC systems and many of them offer space even for semi preparative columns.

But with increasing inner diameter the heat transfer from the air surrounding the column to the whole cross section of the column (filled with the cold mobile phase) becomes more and more difficult. This may result in bad peak shapes, as the radial temperature gradient causes different separation conditions for every part of the sample depending on its distance to the outer diameter.

The following example (see fig. on page 2) illustrates this. Shown is the separation of some flavonoids from a Gingko extract on a 20 mm i.d. YMC Actus column. The chromatogram at the bottom shows the separation at 40°C with direct introduction of the mobile phase into the column. For the separation shown in the middle, the inlet capillary in the oven was extended to allow pre-conditioning of the mobile phase (this measure is often successful in analytical scale). When the eluent in the reservoir bottle was preheated to 40°C (top chromatogram) it gave a chromatogram with excellent peak shapes. Conclusion:

Click for higher resolution image!Conclusion:
Not only the column, but the whole system has to be in a stable and defined state. Preheating of the eluent is therefore an essential step to improving the separation results.
