IC Column Thermostat
|
With the Version 0020 of the "IC Column Heater" Metrohm presents the time-proven column oven in a form which allows even 250 mm long columns to be thermostatted. The control unit remains identical with the Version 0010. The only alteration is to the column heating element which now accomodates, for example, the new A Supp 7 column for the determination of oxohalides. |

The 821 Compact Online IC extends the Metrohm range of industry-conform online ion chromatographs. Up to ten different sample flows can be freely selected for analysis. The design of the 821 Online IC allows the reliable analysis of anions with and without suppression as well as cations down to the lower ppb range. Simple operation, a high degree of data safety, great autonomy and precise results are guaranteed even under very critical environmental conditions, e.g. in production or machine halls. |

With the new
828 IC Dual Suppressor Metrohm has solved the equation 1 + 1 = 3. |

|
||
| As the 828 IC Dual Suppressor is able to eliminate CO2, this opens up a completely new field of applications: the whole performance of the flexible carbonate-bicarbonate system including gradients can be used without any limitations. The injection and carbonate peaks are reduced to the absolute minimum. | ||
PCR Post Column Reactor
|
A small but very powerful accessory: with the "Post Column Reactor" post-column derivatization can be carried out reliably and reproducibly. The color reagent is added by the 752 Pump Unit. The built-in pulsation absorber ensures a stable flow of reagent. Some standard methods require color reactions. For example, with the PCR both chromate and bromate can be determined down to very low concentrations. In the cation analysis sector there is also a range of interesting possible applications as an extension to conductivity detection. | |
| New Columns | ||
Metrosep Carb 1 - 150 (6.1013.010) |
With a capacity of 700 µmol (Cl-) the short and therefore low-capacity version of the Metrosep Carb 1 - 250 (capacity 1530 µmol Cl-) is the preferred separating column whenever retention times which are as short as possible are the primary interest. This column is also suitable for the separation of polysaccharides with a length of up to 30 glucose units. |
|
Metrosep A PCC 1 HC (6.1006.310) and
|
Enlargement of the packing bed has increased the capacity of these two enrichment columns, which are both made completely of PEEK. This high capacity is mainly necessary wherever matrix effects could overload the enrichment column or whenever samples with a high ionic strength are to be analyzed. |
|
Metrosep A Trap 1 (6.1014.000) |
This trap column is a completely new development and efficiently removes even lowest-level anionic contaminants from the eluent. In particular, when working with gradients the use of the trap column guarantees a stable baseline even when the ionic strength changes. |

| Accessories | ||
Gradient mixing spiral (cpl.) 6.2758.000 |
The gradient mixing spiral is a successfully tested accessory for mixing eluents with different strengths for use in high-pressure gradient systems. The "Mixing T" in combination with the one-meter-long coiled 0.5 mm PEEK capillary guarantees optimal and reproducible mixing. | |
Inline Filter PEEK (6.2821.120) |
Inline filters should always be used to reliably protect the separating column and suppressor against any contamination from the eluent, regeneration solution or rinsing solution. The fine 2 µm material of the filter frit removes both particles and bacteria / algae from the solutions. Contaminants can be easily recognized on the filter frit, which can be exchanged quickly and easily (6.2821.130 spare filter frit, 10 pieces). |
