Manufactured by:Welch Materials Inc. based inWest Haven, CONNECTICUT (USA)
Superior quality bare silica and stationary phases synthesized on spherical silica. Rely on Welch’s attention to detail for scalability, reproducibility and high performance. High mechanical strength endures multiple packing/re-packing cycles. Ultra-pure (purity > 99.999% SiO2) silica material with near-zero metals contamination. End-capped materials ensure optimal resolution and peak ...
Manufactured by:Welch Materials Inc. based inWest Haven, CONNECTICUT (USA)
During HPLC analysis, especially when employing gradient elution, some unexpected peaks (usually called “Ghost Peaks”) may appear in the chromatogram. These unwanted peaks often coelute with analytes of ...

Welch Preparative Columns use the same packing materials as our analytical columns. This ensures predictable scale-up and reproducibility. Packed by prep column specialists, our prep HPLC columns deliver excellent stability of column bed for long life and minimal voiding. The theoretical plate number for 10 μm column is greater than 35000/m; for 5 μm column, it is greater than 75000/m, and ...
Manufactured by:Hill-Rom Holdings, Inc. based inChicago, ILLINOIS (USA)

Manufactured by:Kurt J. Lesker Company based inJefferson Hills, PENNSYLVANIA (USA)
Welch: Belt-Drive Standard Vane Pumps: The low pump speed and belt drive combine to reduce operating wear and temperature, thereby reducing maintenance and oil vapor backstreaming. Use these pumps for all general purpose roughing and backing applications that demand longevity. The low pump speed and 'decoupling' of the belt drive makes this 1399 pump run cooler than equivalent direct-drive pumps. ...
Manufactured by:Welch Materials Inc. based inWest Haven, CONNECTICUT (USA)
Sample preparation is one of the most important steps in any analysis process. SPE has become one of the most powerful preparation techniques for the analytical chromatography of various substances, including urine, blood, water, beverages, soil and animal ...
Manufactured by:Welch Materials Inc. based inWest Haven, CONNECTICUT (USA)
UHPLC users have access to a number of high performance choices, including a selection of Ultisil UHPLC (1.8 micron) phases with overlapping selectivity; Xtimate Hybrid UHPLC phases (C18 and C8); and Welch inline filters and guard columns designed for UHPLC applications. All Welch UHPLC columns ...
Manufactured by:Welch Materials Inc. based inWest Haven, CONNECTICUT (USA)
Guard Columns should be deployed in a manner consistent with the column geometry (column diameter), particle geometry (particle diameter), and chemistry (column stationary phase) of the analytical column. ...
