所有用户的好数据
每时每刻
自动校准monitors several key parameters, making sure users are always generating great data. These parameters ensure that users get the best signal-to-noise from their experiments, the fewest artifacts, and the best resolution. AutoCalibrate can be used for all users, no matter the types of samples they run. The parameters that are checked are global parameters used by nearly all NMR experiments,
The key ingredient to generating great NMR data
自动校准的目的是确保所有用户使用Topspin或Iconnmr,无论是初学者还是专家光谱学家,都可以生成出色的数据。
脉冲校准
通过维持质子和碳脉冲长度, we ensure that the majority of all NMR data collected is acquired with the highest signal to noise and the least number of artifacts. Checking the pulse lengths is automated with AutoCalibrate, as is updating the pulse tables and generating update information in the form of a daily report. Go to bed and wake up to calibrated pulses! It couldn’t be any easier.
温度校准
保持恒定,准确的温度将确保复杂光谱中的稳定化学位移和更少的伪影。自动校准将设置适当的流速,校准加热器功率并校正温度。
垫片校准
为自动校准标准样品创建基础3D SHIM图,可以更快,更准确地对用户的样本进行刺激以及对信息进行故障排除
定量
自动校准样品包含非常准确的DSS,特别是0.5mm。使用此材料,我们可以测试QNMR响应并针对其校准,以确定准确性。

QNMR测试 |
自动校准将使用PROF1H参数集来测量DSS的浓度并确保其为0.5mm。然后可以将其与ERETIC II例程和PROV1H参数集一起使用,以测量未知数的浓度。
